My code is attempting to change the number of copies of a sheet printed
part way through a print job.

I wish to print a given page a number of times (perhaps hundreds of
times), and then print a second page a single time. I can do this, but I
don't have my ideal solution, which would (a) keep everything in one
job, (b) not produce a spool file that grew linearly with page count,
and (c) would be reliable.

It's (c) that is problematic with the method I'm trying.

My technique is to build a DEVMODE with the dmCopies member set to the
initial count and pass that to CreateDC. I then later, between an
EndPage and a following StartPage, change the dmCopies value and call
ResetDC with the DEVMODE.

This usually, but not always, works, and the weird thing is, when it
doesn't work, it's when using a network printer rather than a local one.
Does anyone have any idea what alternative mechanism I might use
(excluding doing an EndDoc/StartDoc pair, which works, but causes the
job to split)?

Collating is *not* required.

My first thought is to send PCL to the printer.
Tell the Printer to print the copies, instead of Windows.

Some of these printers are ZPL. Or CPCL. Or other weirdo languages.

(Writing PS or PCL direct is not something that scares me, but the
infrastructure of working out what which particular language a printer
actually supports is daunting. I don't want to rewrite the Windows
printing architecture if I can avoid it.)

It looks, from http://www.codeguru.com/forum/showthread.php?t=151450,
that I'm out of luck.
