My suspicion is that the number of copies is first evaluated in the
pstops filter (and transformed into a suitable PostScript statement there)
and evaluated a second time in the backend that writes the data to
the printer.

To do a detailed analysis, you should supply more detail on how the
printer(s) are configured on both the server and the client(s).
