Question
Multiple Copies of Same Page Content from Various Trays
I use 'gs' to create postscript, and 'setpagedevice' to specify trays.
I print a single page of content (say the file "f.pdf") on each of six different colors of paper, which are pulled from different trays. At the moment, I do this by repeating the filename "f.pdf" six times as an arg to 'gs'. This creates a single postscript file, into which I insert my six 'setpagedevice' commands.
My 65ppm printer has to re-render the same 'f.dpf' postscript six times, which causes it to only produce about 20ppm.
Is there a way to pass a NumCopies specification so that each of my 'setpagedevice' commands switches trays to print the exact same rasterized bitmap? In other words, to write a postscript file that rasterizes 'f.pdf' only once, and still makes use of that cached image for each 'setpagedevice'?
I'm happy to read manuals, but I don't know what technique or feature name(s) I should look for...
thank you,
