The problem is that we cannot rely on actually driving the printer
directly with apsfilter. If the user chose to setup a bounce queue,
the output will be taken by some other filter, and the PS/PCL
sequences for multiple copies might not be preserved.

However, we could use a new variable "HARDWARE_COPIES" that tells
apsfilter to use the printer's copying feature instead of its own
(similar to "HARDWARE_DUPLEX").
