RSCS 3.2.0 Sample Prefix Postscript strings

Product Number: 5684-096 Release 3.2.0

Prefix strings can be defined and used by LPR-type links to initialize the printer, such as select the paper tray or turning on duplexing. When the printer is postscript, the prefix strings can be postscript commands.

The prefix strings can be defined within the configuration file read by the LPRXFORM exit making them selectable via a form.

A sample PIPELINE that could be used to convert commands from EBCDIC to the format required by the prefix strings is: 

          'PIPE < INPUT EBCDIC A',
          '| Strip',
          '| XLATE BA AD',
          '| XLATE BB BD',
          '| XLATE from 1047 to 819',
          '|Specs 1-* C2X 1',
          '|Join * /0D0A/',
          '| > OUTPUT ASCII A'
