Don't worry, PyKota doesn't handle this sort of things for PostScript.
I just said this because I think some jobs like that are possible,
but I've never seen one myself.

For now, the PostScript parser uses max(1, max(allnumcopiesseen)) as the global 
number of copies, and multiplies by number of pages. This may overcharge the 
user, but at least not undercharge and that's what we want ;-)

PyKota's PCL parsers (3,4,5, and then XL/6) correctly handle this on a page per 
page basis though, excepted if the number of copies is set not in PCL but in 
PJL instead (this will be fixed some day)

As you can see, it's a difficult problem... (and PJL can appear in ostScript 
too if I'm not mistaken)
