Doesn't the number of copies go into the .ps file itself?

There _may_ be a template around that gets munged.

Ah, I googled for "postscript language reference" it's all available on 
Adobe's website, but you might prefer not to print it all.

Look for where these are set:
#copies
NumCopies

Page 417 (which Evince thinks is page 431).
