Some suggestions follow. 1 Check that the printer features match the host computer configuration, in particular, the communication protocol. If the printer is connected to the serial port, check the printer 's baud rate, and data bits and parity. See Section 7.4 in Chapter 7 for information on these features. Also check your computer system's documentation. 2 If you have to change the printer 's configuration to match that of the host computer, see Chapter 5. 3 If your printer still does not print your files correctly, see Section 6.2 in Chapter 6. 4 If you are not sure of how to correct the problem, contact your Digital sales representative. 1-20 Installing the Printer 2 ------------------------------------------------------------ Using the Operator Control Panel 2.1 About the LA75 Plus Control Panel This chapter describes how to use the printer 's operating controls. To print files, the control panel switches perform the functions that appear above the switches. Note: The functions on the control panel that appear below the switches are explained in Chapter 5. Using the Operator Control Panel 2-1 2.1.1 Printer Operating Switches and Indicators Ready Indicator and Switch The Ready switch puts the printer on-line or off-line. When the Ready indicator (RDY) lights up, the printer is on-line and ready to print. When the Ready indicator is blinking, the printer is off-line and will not print. If you press the Ready switch while the printer is printing (putting it off-line), the LA75 Plus will complete the line it is printing, stop, then move the paper until the last line is visible. Serial Port Indicator The Serial Port indicator lights up when the printer receives data from the serial port. When the Serial Port Indicator is not lit up, the printer receives data from the parallel port. Fault Indicator The Fault indicator is amber. It lights up when the paper supply is exhausted or nearly exhausted, or if there is a mechanical problem, and flashes continously when the printer finds an electronic problem. (See Section 6.2.3 in Chapter 6 to find the probable cause of the problem, as well as suggestions for correcting the problem.) Quiet Indicator The Quiet indicator is green. It lights up when the printer is turned to Quiet mode. 2-2 Using the Operator Control Panel Quiet/Quality Switch When the printer is in Ready mode, pressing the Quiet/Quality switch puts it into Quiet mode. When the printer is off-line, (the Ready indicator (RDY) is blinking), the Quiet/Quality switch allows you three choices of print quality: 1 Letter Quality (LQ), which prints at 83 characters per second (CPS). 2 Draft Quality (DQ), which prints at 250 CPS. In both cases, an indicator lights up next to the print quality you have selected. 3 If no indicator lights up, the print quality is controlled through software commands. The LA75 Plus has one other print quality, Near Letter Quality (NLQ), which prints at 125 CPS. This mode is only selectable through sofware commands. Note: All CPS speeds listed in this guide are quoted at their maximum burst speeds (Normal Mode). For more information on CPS, see Section 7.5 in Chapter 7. Protocol Indicator and Switch The Protocol switch lets you change the way the printer communicates with your computer system. This switch is only operative when the printer is in a paused state, and a print job has finished. (There is no data left in the print buffer.) Press this switch to toggle between DEC protocol and IBM X24E protocol. When DEC LED is On, DEC mode is selected; when DEC LED is Off, IBM mode is selected. The protocol can also be changed by the application software. Line Feed (LF) Switch The LF switch advances the paper in the printer one line at a time. Continued pressure on the switch advances the paper a number of lines. Form Feed (FF) Switch The FF switch advances the paper in the printer to the top of the next form. Using the Operator Control Panel 2-3 3 ------------------------------------------------------------ Loading the Paper 3.1 Paper Controls The levers and controls described in this section are used for loading and positioning paper in the printer. Loading the Paper 3-1 3-2 Loading the Paper Parking Lever The parking lever (7) controls the autopark function. This function is used to move pinfeed paper into the park position before single-sheet loading. Bail Bar The bail bar (5) holds the paper against the platen (9). The red marks (6) on the bail bar indicate the print area for a standard sheet of paper. Use these marks to position the paper corrrectly. Platen Knob The platen knob (4) is only used to clear paper jams. Do not use it in any other circumstances. Paper Release Lever The paper release lever (3) controls the paper drive system. Pull the lever towards the front of the printer for tractor feed. Push the lever towards the back of the printer for friction feed. Tractor Release Levers The tractor release levers (2) are used to position the entire tractor unit for a paper-feed operation. Tractor Clamps The tractor clamps (1) allow you to adjust the position or location of the tractors for different paper sizes. Pull the clamp towards the front of the printer to move the tractor to the left or right. Push the clamp towards the back of the printer to lock the tractor in place. Tractor Stop The tractor stop (8) prevents the left tractor from being moved too far to the right. Loading the Paper 3-3 Printhead Adjustment Lever The printhead adjustment lever changes the printhead position to allow for different thicknesses of paper, and for forms or envelopes. The lever can be moved to four positions to vary the distance between the printhead and the platen. See Section 3.3 in this chapter for more information. 3-4 Loading the Paper 3.2 Loading Paper There are three ways to load paper for the LA75 Plus which are illustrated in the cross-section diagrams later in this section. ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ Load pinfeed paper from the back of the printer (Factory default). ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ Hand feed single sheets 1 from the back of the printer. ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ Load pinfeed paper through the printer 's bottom slot. Note: Bottom Loading is intended for printing applications using forward paper motion only. Typically, bottom loading is most appropriate for loading "difficult" paper (for example "sticky" labels). It is the least frequently used of the three loading methods. Note: Using the printer 's bottom slot requires a special printer table or stand. Contact your Digital sales representative for ordering information. For applications requiring reverse paper motion to achieve printing functions such as bolding, underlining, and superscripting or subscripting, load the paper from the back of the printer. The new LA75 Plus features described in Section 3.2.1.1, Viewing the Last Printed Line and Section 3.2.1.2, Document on Demand are only possible with Rear Loading. Table 3-1 illustrates Digital's recommendations on using the three methods. Table 3-1 Loading Methods and Types of Paper ------------------------------------------------------------ Method Type of Paper ------------------------------------------------------------ Rear Loading (Section 3.2.1) Pinfeed Paper Single-sheet Loading (Section 3.2.2) Single Sheets/Envelopes Bottom Loading (Section 3.2.4) Pinfeed Paper -Labels/Multipart ------------------------------------------------------------ ------------------------------------------------------------ 1 See also the LA75 Plus Companion Printer Sheet Feeder Guide Loading the Paper 3-5 Loading Methods Diagram A illustrates the Rear Pinfeed Loading method, Diagram B the Single- sheet Loading method, 1 . and Diagram C the Bottom Pinfeed Loading method. The three methods are discussed respectively in Section 3.2.1, Section 3.2.2 and Section 3.2.4 later in this chapter. ------------------------------------------------------------ 1 See also the LA75 Plus Companion Printer Sheet Feeder Guide 3-6 Loading the Paper 3.2.1 Rear Loading 1 Unlock only the clamp on the right tractor by pulling the clamp towards the front of the printer. Note: The left tractor has been factory set so that the left edge of the paper (column 1) lines up correctly with the printhead when it starts printing. Digital recommends that you do not unlock the left tractor clamp. Only unlock it if, for some reason, the leftmost character does not line up with the edge of the paper. 2 Open both tractor doors. 3 Align the pinfeed holes on both edges of the paper with the tractor pins. Close the tractor doors to secure the paper. Loading the Paper 3-7 Note: The red marks on the bail bar indicate the print area for a standard sheet of paper. Use these marks to help position the paper correctly. 4 Readjust the right tractor position by moving it to the right so that the paper extends between the two tractors. (The pinfeed holes should not be mis-shaped by too much tension on the paper.) Lock the right tractor by pushing the tractor clamp towards the back of the printer. 3-8 Loading the Paper 5 Pull the paper release lever towards the front of the printer to set the printer in tractor mode. Loading the Paper 3-9 6 Replace the access cover and the paper cover. 7 Pull out the wire paper-separator (A). Note: The printer will not work if the covers are not on, or if they are replaced incorrectly. 3-10 Loading the Paper Activating the Automatic Paper Feed You can now advance the paper to the print position by activating the automatic paper feed as follows. ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ Turn the power switch to 1 (on). All the indicators light up on the Control Panel. The printhead moves to the center, to the print position, and the paper automatically moves under the platen, also to the print position. ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ If the power was already on, press FF to load the paper. You are now ready to print. Loading the Paper 3-11 3.2.1.1 Viewing the Last Printed Line This section and Section 3.2.1.2 describe two LA75 Plus features that are available using the Rear Loading method. There are three methods to advance the paper to see the last printed line. (This procedure applies only to pinfeed paper.) To ease readability, the paper support should be in the raised position. A When printing has ended and the printer is in the Ready state: 1 Press the Ready switch. The paper advances so that the last printed line can be seen above the tear-off line. 2 Press the Ready switch again. The paper returns to the previous printing position. B When the printer is printing: 1 Press the Ready switch. The printing stops, and the paper advances so that the last printed line can be seen above the tear-off line. 2 Press the Ready switch again. The printer moves back, and printing continues from the next line C If you select Automatic Advance, the paper will advance for viewing if no data is received for two seconds. The paper will move back as soon as the next data is received. Note: You cannot view the last printed line if the end of the paper has been detected. 3-12 Loading the Paper 3.2.1.2 Document on Demand If the last character received by the printer was a Form Feed, or if you pressed FF at the end of the last printed job, you can make use of the Document on Demand feature and so avoid wasting paper before the next printed job. Document on Demand works in the same way as Viewing the Last Printed Line. Two modes can be selected in the Set-up menu: Automatic and Manual (the factory default). ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ Automatic When two seconds have elapsed since the printer received the last piece of data (FF), the paper perforation moves on to the tear blade. Tear off the paper. On the receipt of new data, the paper moves back to its previous position (the first printable line). ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ Manual Press the Ready switch to move the paper perforation on to the tear blade. Tear off the paper. Press the Ready switch again to move the paper back to its previous position (the first printable line). Note: To use Document on Demand correctly, make sure that the value of the printer 's form length matches the physical paper size. 1 . ------------------------------------------------------------ 1 For selecting form length (Generic Feature 2 in Set-up mode), see Section 7.5 in Chapter 7 Loading the Paper 3-13 3.2.2 Single-sheet Loading 1 Turn the power switch to 1 (on). All indicators light up on the Control Panel. The printhead moves to the center, to the print position. 2 If (and only if) there is pinfeed paper in the printer, pull the parking lever all the way forward to the autopark position. The paper moves away from the print position and remains in the tractors. Note: This autopark feature allows you to reverse the paper only two page lengths (15 inches, 38.1 centimeters) at a time. 3-14 Loading the Paper 3 Raise the paper support and secure it in place. Pull out the paper separator. Loading the Paper 3-15 4 Move the paper release lever towards the back of the printer so that it is in friction mode. 5 Place a single sheet of paper on the paper support so that the paper is resting just under the platen. If the Fault indicator goes out when the paper is inserted, move the paper away from the platen until the Fault indicator lights up again. 6 Move the paper-edge guide to the right until it is aligned with the arrow on the paper support. 3-16 Loading the Paper 7 Advance the paper to the print position by activating the Automatic Paper Feed. To do this, press the FF switch on the control panel. The Fault Indicator turns off. You are now ready to print on the single sheet. 3.2.2.1 Printing Multiple Single Sheets To print multiple single sheets, use the Automatic Sheet Feeder option. Full details of the installation and use of the Automatic Sheet Feeder (LA75 PlusX-SF) are included in the LA75 Plus Companion Printer Sheet Feeder Guide. Loading the Paper 3-17 3.2.3 Switching to Bottom Loading Note: Using the printer 's bottom slot requires a special printer table or stand. Contact your Digital sales representative for ordering information. 1 Make sure the power switch is set to 0 (off). 2 Remove the access cover and the paper cover. 3 Move the left tractor release lever towards the front of the printer until it locks. 3-18 Loading the Paper 4 Move the right tractor release lever towards the front of the printer and pull the tractor unit up. The tractors are now in a horizontal position. Loading the Paper 3-19 5 Unlock the tractor clamp on the right tractor by pulling the clamp towards the front of the printer. Note: The left tractor has been factory set so that the left edge of the paper (column 1) lines up correctly with the printhead when it starts printing. Digital recommends that you do not unlock the left tractor clamp. 6 Open both tractor doors. 3-20 Loading the Paper 7 Move the paper release lever towards the front of the printer to set the printer in tractor mode. Loading the Paper 3-21 3.2.4 Bottom Loading 1 After opening the tractor doors, insert the paper through the bottom slot of the printer. Note: To prevent skewing, position the paper so that it feeds straight into the bottom of the printer. Note: Using the printer 's bottom slot requires a special printer table or stand. Contact your Digital sales representative for ordering information. 2 Pull the paper up between the platen and the clear plastic smudge guard, and onto the tractors. 3-22 Loading the Paper 3 Align the pinfeed holes on both edges of the paper with the tractor pins of both tractors. Close the tractor doors to secure the paper. Note: The red marks on the bail bar indicate the print area for a standard sheet of paper. Use these marks to help position the paper correctly. 4 Readjust the right tractor position by moving it to the right or left so that the paper extends between the two tractors. (The pinfeed holes should not be mis-shaped by too much tension on the paper.) Lock both tractors in place by pushing the clamps towards the back of the printer. Loading the Paper 3-23 5 Adjust the paper by pulling it down from beneath the printer 's bottom slot. 3-24 Loading the Paper 6 Manually adjust the top of the form. 7 Replace the access cover and the paper cover. Note: The printer will not work if the covers are not on, or if they are replaced incorrectly. You are now ready to print. Note: To return to rear loading, release the tractor unit by pulling both tractor release levers towards the front of the printer. Click the tractor unit into place. Loading the Paper 3-25 3.3 Adjusting the Printhead for Paper Thickness For single-part pinfeed paper, and single-sheet hand-fed paper: Push the printhead adjustment lever all the way towards the platen. For multipart paper or envelopes: Pull the lever towards the front of the printer. 3-26 Loading the Paper 4 ------------------------------------------------------------ Using Fonts This chapter describes how to insert and access the optional font cartridges available for the LA75 Plus. 4.1 Using the Optional Font Cartridges A set of font cartridges is available which cover different printing needs. Each cartridge works both in DEC and Emulation protocols. For details of these cartridges see Section 7.6 in Chapter 7. Note: The print density must be set to Letter quality when you are using typestyles from the font cartridge. When you select Draft quality, the printer uses the internal draft typestyles. 1 Make sure the power switch is set to off (0). Caution: If you do not set the power switch to off before inserting the font cartridge, you could damage the cartridge. Using Fonts 4-1 2 Insert the cartridge, making sure it is firmly in place. Caution: The font cartridge has a key and can be inserted only one way. Do not try to force the cartridge into place. 3 Power On the printer and enter the user set-up mode to select the type style or character sets provided by the cartridge. (Refer to the notice on the cartridge.) 4-2 Using Fonts 5 ------------------------------------------------------------ Configuring the Printer 5.1 What is Configuration? This chapter describes how to set up or configure the LA75 Plus, so that the printer and your computer system can communicate correctly with each other. Communication between the two requires that both the computer operating system and the printer have the same communication settings or features. The most important of these are protocol, baud rate, and data bits and parity. You may also need to change some of the printer 's other features depending on your hardware and software requirements. (See Chapter 7 for a complete list of printer features.) Set-up mode allows you to access the LA75 Plus's configuration memory. The memory stores a list of all the printer 's features and values, as well as the values that you have chosen to run the printer. The set-up controls which are discussed in Section 5.3, allow you to access set-up mode. Configuring the Printer 5-1 5.1.1 Determining the Printer's Configuration Check your computer system's documentation to determine what your system requirements are for protocol, baud rate, and data bits and parity. (These are, respectively, Generic Features 1, 7, and 8 in Set-up.) You can see what is programmed into your LA75 Plus's set-up memory by following these instructions: 1 Turn the power switch to 0 (off). 2 Press and hold the Set-up switch while you set the power switch to 1 (on). The LA75 Plus prints a list of what is in its set-up memory. See the tables in Section 7.4 in Chapter 7 for examples of what information is stored in set-up memory. 3 Press the Set-up switch to exit Set-up mode. 4 Compare the printer 's current configuration with the requirements of your computer or video terminal. Read Section 5.3 if you need to change the printer 's set-up memory. 5-2 Configuring the Printer 5.2 Features and Values Each of the LA75 Plus's features stored in its set-up memory has at least two values. (See Section 7.4 in Chapter 7). A value is an option or choice within each feature. The features are organized into three groups as follows: ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ Generic ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ DEC (specific to Digital protocol) ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ X24 (specific to IBM Proprinter X24E) When you are in set-up mode, you can change the value for any feature. Changing the set-up memory changes the way the printer runs and how it communicates with your host computer. The following example illustrates the difference between a feature and a value: The set-up menu gives you seven choices for the baud-rate feature. Baud rate is the speed at which the printer can receive data from your host computer. The printer 's baud rate is factory-set at 4800 bits per second. If your host computer 's baud rate is set at 1200 bits per second, you will need to change the LA75 Plus's baud rate from 4800 to 1200 in order to have accurate communication between your host computer and the printer. In this example, baud rate is the feature; 4800 and 1200 are the values. Configuring the Printer 5-3 5.3 Set-up Mode Switches and Indicators In set-up mode, the control panel performs the functions that appear in letters and arrows below the switches. Set-up Switch To put the printer in set-up mode, press the Set-up switch while turning the printer on. After you have changed the printer 's configuration, press the Set-up switch again to save the new values and to exit set-up mode. Up-arrow and Down-arrow Switches Press the Up-arrow and Down-arrow switches respectively upwards and downwards through the features when you are setting the printer 's configuration. Right-arrow and Left-arrow Switches Press the Right-arrow and Left-arrow switches to scan respectively forwards and backwards through the values when you are setting the printer 's configuration. 5.3.1 Changing the Printer's Configuration (Set-up Mode) Note: Before beginning the set-up procedure, make sure that the power switch is set to 0 (off) and that paper is advanced to the print position. 1 Press and hold down the Set-up switch while setting the power switch to 1 (on). The Serial Port and Draft indicators flash. The printer automatically does the following: ------------------------------------------------------------ Prints a list of the features and values stored in its memory. (See Section 7.4 in Chapter 7.) ------------------------------------------------------------ Prints the first feature in the list (Protocol: DEC Emulation, or port-dependant). 2 Press the Right-arrow or Left-arrow switch to select the next or previous value. 3 Press the Up-arrow or Down-arrow switch to access the feature you wish to change. 5-4 Configuring the Printer Note the following: ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ If the first value Protocol is set to DEC, only the DEC and Generic group features are accessible in Step 3. ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ If the first value Protocol is set to X24, only the X24 and Generic group features are accessible in Step 3. ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ If the communication is port-dependant, all features are accessible. 5.3.2 Saving New Values and Exiting Set-up Mode Press the Set-up switch once to store your set-up changes in the printer 's memory. The printer automatically returns to print mode. Note: If the power is turned off before the Set-up switch is pressed, no changes are stored in the printer 's memory. 5.4 Protocol Selection The protocol that is active at power-up is selected through Generic Feature 1 in Set-up. When this feature is selected, the protocol is determined at power-up by the following rules: ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ If the Port Selection feature is set to "Serial Port", the DEC protocol is selected. ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ If the Port Selection feature is set to "Parallel Port", the IBM Proprinter protocol is selected. ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ If the Port Selection feature is set to "Automatic", the first active port will determine the selected protocol: ------------------------------------------------------------ If the first active port is the serial port, the DEC protocol is selected. ------------------------------------------------------------ If the first active port is the parallel port, the IBM Proprinter protocol is selected. ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ After a protocol is selected, a new selection can only be done through software commands, or through the Protocol switch on the control panel. Configuring the Printer 5-5 6 ------------------------------------------------------------ Maintaining the Printer 6.1 General Maintenance The printer does not need preventive maintenance. The casing of the printer and the platen will need cleaning from time to time. Digital's computer-accessories catalog, DECdirect, lists suitable cleaners for these tasks. Always use the cleaners in accordance with the instructions on the cleaners.. Paper Select the correct kind of paper for the job. Always make sure to position paper squarely and set it tightly around the platen. Also make sure that the printhead adjustment lever is in the correct position (See Section 3.3 in Chapter 3). See Section 7.5 in Chapter 7 for paper specifications. To remove paper from the printer, use the FF switch. Ribbon Cartridge and Printhead Keep samples of early printouts to help you know when to replace the ribbon cartridge and printhead. Use only Digital-approved ribbon cartridges in the printer. (Other cartridges may not give the same performance and may shorten the life of the printhead.) See Section 6.3 in this chapter for information on how to replace the ribbon cartridge, See Section 6.2 for tips on recognizing when to replace the ribbon cartridge and printhead, or when to contact your service representative. Maintaining the Printer 6-1 6.2 Correcting Simple Problems This section lists possible fault symptoms and suggests tests and actions to help you clear those symptoms. How to Use This Section 1 Find the category in which your problem occurs. For example, if the print appears very light on the paper, look at Section 6.2.4, Print-related Problems. 2 Find the symptom description that most closely matches the printer symptom. In this example you would look at the symptom "Print faint or of poor quality." 3 Try the first suggestion under that heading. 4 If the suggestion does not cure the problem, try the next suggestion. 5 If none of the suggestions enable you to continue printing, or if the fault is not listed, you will need to contact your Digital sales representative. Each time the printer is switched On, the indicators flash slowly for approximately two seconds while the internal self-tests are run. Look at all the indicators to make sure that they are all working. (If an internal fault is detected, the Fault indicator will flash faster than the other indicators.) If any indicators are faulty, or if the Fault indicator flashes, contact your Digital sales representative. Warning: It is assumed that the reader is not qualified to work on, or with, high-voltage electricity. Interpret the suggestions in accordance with your qualifications in electrical technology. 6.2.1 Power-related Problems ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ No indicators come On when power is switched On. i Check that the power cord and plug are securely fitted to the printer. ii Ask for the power connector connections (and fuse, if fitted) to be verified. iii Ask for the building electrical supply to be verified. ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ ------------------------------------------------------------ Ready indicator is flashing; Fault indicator is flashing (1 second period), and does not respond when the Ready switch is pressed. i Is the access cover fitted and seated correctly?

B-2 Printing Control Characters C ------------------------------------------------------------ DEC PPL2 Quick Reference This appendix contains basic information on the DEC PPL2 commands that are supported in the LA75 Plus. It also contains the character set code tables supported by the LA75 Plus in the DEC PPL2 protocol. The commands are listed by function in the following order: Positioning controls Sheet size and margins Type size and spacing, managing implicit cursor motion Font management and attribute selection Tabs Character set selection Reports Miscellaneous This guide should be used in conjunction with the Digital Ansi-compliant Printing Protocol Level 2 Programming Reference Manual and the Digital Ansi-compliant Printing Protocol Level 2 Programming Supplement. Characters used in control functions appear in monospaced type. Table D-1 explains some of the conventions used. A pair of numbers separated by a slash (/) character indicates Column/Row notation. This notation refers to the location of a character in a standard code table, such as ASCII. Spaces appear between characters in sequences for clarity; they are not part of the format. Space is designated as "SP" when it is part of the format of a command or sequence. DEC PPL2 Quick Reference C-1 The following conventions are used in the command listings: Table C-1 Conventions ------------------------------------------------------------ ESC Escape (1/11), introduces an escape sequence CSI Control Sequence Introducer (9/11), introduces a control sequence. CSI can also be represented by the equivalent escape sequence ESC [ (1/11 5/11). DCS Device Control String (9/0), introduces a device control string. DCS can also be represented by the equivalent escape sequence ESC P (1/11 5/0). ST String Terminator (9/12) indicates the end of a control string. ST can also be represented by the equivalent escape sequence ESC \ (1/11 5/12). Pn Numeric parameter, or number of units that specify a distance or quantity pertaining to the escape sequence, control function or control string. Ps Selective parameter, or one which identifies a list of options pertaining to the specific command. If ">" (3/14) or "?" (3/15) occurs at the beginning of a string of parameters, the parameters that follow are Digital private parameters. ">" or "?", if present, must occur only once at the beginning of the parameter string. I n Intermediate character -- component of an escape sequence, control sequence or control string F Final character -- component of an escape sequence, control sequence or control string SP Space (2/0) ------------------------------------------------------------ Note Both numeric and selective parameters are interpreted as unsigned decimal integers, with the most significant digit sent first. For instance, the value 16 is coded as "16" (3/1 3/6). Leading zeros are allowed but are ignored. Plus and minus signs are not allowed.

This guide should be used in conjunction with the Digital Ansi-compliant Printing Protocol Level 2 Programming Reference Manual and the Digital Ansi-compliant Printing Protocol Level 2 Programming Supplement. Characters used in control functions appear in monospaced type. Table D-1 explains some of the conventions used. A pair of numbers separated by a slash (/) character indicates Column/Row notation. This notation refers to the location of a character in a standard code table, such as ASCII. Spaces appear between characters in sequences for clarity; they are not part of the format. The following conventions are used in the command listings: Table D-1 Conventions ------------------------------------------------------------ ESC Escape (1/11), introduces an escape sequence n1 n2 A 2 byte number of data beginning with the next byte, low byte followed by high byte. This number indicates the number of parameters in the Escape Sequence.
