2 Physical Page Characteristics of the LA75 Plus Companion Printer This chapter explains how the LA75 Plus Companion Printer handles the transfer of the logical page in memory to the physical paper. Topics include: • Paper handling, Section 2.1 • Response to a Form Feed request, Section 2.2 • Horizontal text resolution, Section 2.3 • Vertical text resolution, Section 2.4 • Limits on partial line motion, Section 2.5 • Tab support, Section 2.6 • Automatic sheet feeder control, Section 2.
PAGE 22
Physical Page Characteristics of the LA75 Plus Companion Printer 2.1 Paper Handling The LA75 Plus Companion Printer uses the form length, as determined by the setup feature or by the Set Lines Per Page (DECSLPP) command, to compute the tops of forms other than the first. Fanfold Paper — Bottom Feed/Rear Output (Pull Tractor Mode) In this mode there is no autoload function, so the printer cannot detect the top of form. The power-up paper position is assumed to be the top of form.
PAGE 23
Physical Page Characteristics of the LA75 Plus Companion Printer 2.2 Response to Form Feed (FF) Fanfold Paper — Bottom Feed The LA75 Plus Companion Printer assumes that the paper position prior to any paper motion is the reference for the first top of form. Form Feed (FF) advances the paper to the next top of form. Cut Sheet Paper — Manual Feed If paper is not currently loaded, Form Feed (FF) is stored and does not load paper.
PAGE 24

13 Sixel Graphics Considerations on the LA310 MultiPrinter This chapter explains the graphics resolution capability of the LA310 MultiPrinter. 13.1 Graphics Resolution Since the LA310 does not support a physical horizontal resolution of 1/660", it needs to ‘‘fall back’’ to a different grid size when some grid sizes are requested. Table 13–1 shows the values that the LA310 uses for the macro parameter (Ps1) of the Sixel Graphics mode protocol selector.
PAGE 82
Sixel Graphics Considerations on the LA310 MultiPrinter 13.1 Graphics Resolution The printer attempts to preserve the requested aspect ratio without exceeding the requested horizontal grid size (as defined by Pn3 of the protocol selector). The aspect ratio is provided by Ps1 or Set Raster Attributes (DECGRA). First the printer ensures that the aspect ratio is one of the supported values (1:1, 2:1, 2.5:1): • If aspect ratio is less than 1.

PAGE 92
Physical Page Characteristics of the LA600 MultiPrinter 16.1 Paper Handling Fanfold Paper — Front Feed/Rear Output (Tractor Mode) Paper in parked position loads automatically when data is received. At power-up, when the LA600 MultiPrinter is not at line 1, column 1, or in parked position, the printer performs a conditional Form Feed to reset Top of Form (TOF). The LA600 MultiPrinter can detect the top of the first form only.
PAGE 93
Physical Page Characteristics of the LA600 MultiPrinter 16.2 Response to Form Feed (FF) Note If the paper source is modified via the command DECASFC or the Operator Panel, the current cut sheet is ejected and the fanfold paper is parked automatically. 16.3 Automatic Sheet Feeder Control To control its optional Automatic Sheet Feeder (ASF), the LA600 MultiPrinter uses the Automatic Sheet Feeder Control (DECASFC) command.
PAGE 94
Physical Page Characteristics of the LA600 MultiPrinter 16.4 Paper Tray Selection (DECSITF) 16.4 Paper Tray Selection (DECSITF) The LA600 supports the command Select Input Tray Failover (DECSITF). When all of the paper trays in the composite tray definition are empty, a ‘‘paper out’’ condition occurs. Printing resumes when any of these trays is reloaded. The LA600 supports the Ps2–Psn values from 1 to 3, with a maximum of 3 parameters. The printer does not support the combination Ps2, Ps3=1,3.
PAGE 95
Physical Page Characteristics of the LA600 MultiPrinter 16.6 Printhead Gap Control (DECPHGC) • The paper source has changed. • Paper is inserted manually. • Fanfold paper has moved from the parked position. • Power-up has occurred. • Printing resumes after an offline condition, which the resulted from either user action on the Start/Stop key or a fault. • A DECPHGC command is received with Ps=0 on the previous page or prior to loading the paper.

21 Sixel Graphics Considerations on the LA600 MultiPrinter This chapter explains the graphics resolution capability of the LA600 MultiPrinter. 21.1 Graphics Resolution Since the LA600 MultiPrinter does not support a physical horizontal resolution of 1/720", it needs to ‘‘fall back’’ to a different grid size when some grid sizes are requested. Table 21–1 shows the values that the LA600 uses for the macro parameter (Ps1) of the Sixel Graphics mode protocol selector.
PAGE 154
Sixel Graphics Considerations on the LA600 MultiPrinter 21.1 Graphics Resolution The printer attempts to preserve the requested aspect ratio without exceeding the requested horizontal grid size (as defined by Pn3 of the protocol selector). The aspect ratio is provided by Ps1 or Set Raster Attributes (DECGRA). First the printer ensures that the aspect ratio is one of the supported values (1:1, 2:1, 2.5:1): • If aspect ratio is less than 1.

A Printer Communication Interfaces This appendix provides information on the serial and parallel interfaces of the printer and describes the mechanism for the automatic port selection. Sections include: • Data communication interfaces, Section A.1 • The serial port, Section A.2 Serial data character format, Section A.2.1 Serial data synchronization, Section A.2.2 • The parallel port, Section A.3 • Automatic port selection, Section A.4 A.
PAGE 160
Printer Communication Interfaces A.2 The Serial Port A.2.1 Serial Data Character Format The serial data character format used by the printer is the format used for normal asynchronous transmission, that is: • A start bit (space) • 7 or 8 data bits (1 = mark, 0 = space) • A parity bit (selectable) • One or more stop bits During setup, the use of the parity bit (on or off) and the number of data bits (7 or 8) that you assign must agree with the computer to which the printer is connected.

XON/XOFF Control While XON/XOFF is enabled, DTR remains high.
PAGE 162
Printer Communication Interfaces A.2 The Serial Port DTR Handshaking Control When DTR handshaking protocol is selected, the DTR (Data Terminal Ready) signal of the serial interface is raised and lowered to control data flow, as follows: • When just powered up and ready, the printer forces DTR high, signaling to the data source that transmission may begin.
PAGE 163
Printer Communication Interfaces A.4 Automatic Port Selection A.4 Automatic Port Selection When the Communication Port Selection feature is set to ‘‘automatic’’ (for the LA75 Plus and the LA310 MultiPrinter) or to ‘‘shared’’ (for the LA600 MultiPrinter) during setup, either the serial or parallel port automatically becomes active when valid data is received on it. In the case of the serial port, valid data means data without a parity error.
PAGE 164
Printer Communication Interfaces A.4 Automatic Port Selection • As long as there is data in the printer’s input buffer, the currently active port remains active. • If the input buffer of the active port remains empty for 2 seconds, the port is disabled by placing it in the standby state. At this time the other port is enabled.

B Comparison of DEC PPL2 Commands by Printer Appendix B compares the DEC PPL2 commands supported by the Digital Level 2 printers. The LA50, a Level 1 printer, is included for reference. Each command is described as belonging to a level of the protocol or an extension to the protocol. Each level of the protocol includes the commands of the lower-numbered levels of the protocol. Therefore, level 2 of the protocol (DEC PPL2) includes the commands of level 1 (DEC PPL1).

C DEC PPL2 Command Dictionary Supplement This appendix provides the definition of new DEC PPL2 commands not listed in the Digital ANSI-Compliant Printing Protocol Level 2 Programming Reference Manual. These commands are implemented on some DEC PPL2 printers only (see Appendix B).
PAGE 184
DECLANS — Load Answerback DECLANS — Load Answerback Loads a coded string as the Answerback message and optionally stores it into nonvolatile RAM (NVRAM). Source: Symbiont Destination: Levels 1, 2, 3 Exception Format Without password: DCS Ps1 v D ... D ST 9/0 *** 7/6 encoded_message_string 9/12 With password: DCS Ps1 ; Pn2 ; Pn3 v D ...
PAGE 185
DECLANS — Load Answerback The printer supports a method to lock the answerback message via the DEC PPL2 protocol. A decimal password can be given along with the answerback message being loaded. When a password is loaded into the printer, it must be specified in a subsequent DECLANS command in order to change the answerback message in the future. The password as well as the answerback are stored in non-volatile memory. This feature is selected with a Ps1 value of 3.

DECSITF — Select Input Tray Failover DECSITF — Select Input Tray Failover Designates the input trays used for failover. Source: Symbiont Destination: Level 2 Exception, Level 3 Extension Format CSI Ps1 ; Ps2 ; 9/11 *** 3/11 *** 3/11 . . . Psn SP w *** *** 2/0 7/7 Description This command defines the paper tray failover rules for the printer. A composite tray may be defined by the DECSITF command, across which paper tray failover may occur.
PAGE 190
DECSITF — Select Input Tray Failover This command only affects sheets printed subsequent to the receipt of this command. DECSITF cannot be used to clear a ‘‘paper out’’ condition. A member of the composite tray need not be present when the command is received, but must be present at the time of failover, or the device considers the next tray in the composite tray definition. When all of the paper trays in the composite tray definition are empty, a ‘‘paper out’’ condition occurs.
