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 switch-
ing 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 emu-
lation 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.
