To set a parallel or INA port for binary data:
1. To switch to binary mode, enter the following (ASCII off):
%!PS
true 0 startjob
currentsystemparams /CurInputDevice get
<< /Filtering /None >> setdevparams
2. To switch to ASCII mode, enter the following (Binary off):
%!PS
true 0 startjob
currentsystemparams /CurInputDevice get
<< /Filtering /InterpreterBased >> setdevparams
Note that these files are port specific. Thus if you send the files to the printer using its parallel port, only
the parallel port is affected.
Also note that Optra S 81.10 base code does not support the /Filtering parameter. Base code 85.21 and
later in all Optra SC and Optra K code versions do support the /Filtering parameter. Optra + base code 52.04
and later releases all support switching from binary to ASCII mode.
Printers with Automatic Emulation Switching
A <CTRL+D> character on the first line of a trigger normally indicates the end of one job and the
beginning of another. This prevents mixups in print jobs.
Some printers implement an Automatic Emulation Switching (Auto Switch) feature that automatically
recognizes what emulation it requires to process a job. In this case, when the file containing your trigger is
in ASCII, the printer does not recognize the first few lines as a PostScript program (your trigger). Instead it
makes the printer enter ASCII emulation. To prevent this, you must modify the trigger as follows to force
the printer to switch to PostScript.
<ESC>%-12345X
<ESC>%-12345X@PJL JOB
@PJL ENTER LANGUAGE = POSTSCRIPT
