I do not know much about ghostscript but do we know what this change
does and what the real problem was? Was it the PDFSETTINGS=/printer or
the DoNumCopies? What does the change really do?
A half hour of Internet research didn't turn up much:
-dPDFSETTINGS=/screen (screen-view-only quality, 72 dpi images)
-dPDFSETTINGS=/ebook (low quality, 150 dpi images)
-dPDFSETTINGS=/printer (high quality, 300 dpi images)
-dPDFSETTINGS=/prepress (high quality, color preserving, 300 dpi imgs)
-dPDFSETTINGS=/default (almost identical to /screen)
I do not know what color preserving means.

It's been a while since I worked in printing support and had to deal
with PostScript/PDF/ghostscript stuff, but I'd wager a guess that
/prepress is for professional printing, and "color preserving" in that
context probably means that ghostscript should not attempt to apply a
color profile when processing the file, as professional printing
equipment usually has its own methods of color calibration.
Does that sound like it makes sense? ;-)
