The rtestd Interface

The rtestd interface is for use by printers that are controlled by the standard RTE printer drivers. This interface issues the standard control requests or escape sequences for controlling printer devices and supports the standard set of EXEC control word bits for the RTE printer drivers DD*12, DDC12, DDC00, and DDC01.

Two printer model files are supplied for this interface: generic and pcl. The pcl model file is for printers that support the HP Printer Control Language (PCL). The generic model file is for printers that do not support PCL.

Features Common to generic and pcl Models

This section lists options common to both the generic and the pcl models of the rtestd interface. The options that are supported only by the pcl model are listed in the following section. Printer interface options are specified in the lp program runstring preceded by a -o. The options are:

DDevice Handling:

ccThe files contain FORTRANstyle carriage control in column 1. Use of the •raw" (or •r") or •nolnc" options negates the effect of this option.

kc

The files include EXEC control word headers. The files must have been created by

 

the ON command of the SP spooler with the KC option specified. These headers

 

specify the control word flags that were used in the redirected EXEC/XLUEX

 

writes and preserve information on control requests that were sent to the redi

 

rected device. This option has no effect on type 1 files.

rFile data should be sent unretouched to the printer. Uses transparent (also known

raw as honesty mode) writes to the device, that is, automatic CRLF adding and trailing underscore processing does not occur. This option causes type 1 files to not be pro cessed in UNIX text file format, where lines are separated by linefeed characters (see below). This option cancels the effect of the •cc" option.

nolnc Do not treat an underscore at the end of a record as a line continuation character. A CRLF is still printed at the end of each record. Uses transparent (also known as honesty mode) writes to the device. This is the same as using the •raw" option, except that a CRLF sequence is sent at the end of each record. This option cancels the effect of the •cc" option.
