--- Comment #3 from Piotr Caban piotr.caban@gmail.com --- (In reply to Dmitry Timoshkov from comment #2)
Do we really need to be compatibe with Windows and ignore the dmCopies field when interpreting EMF?
It's possible to reprint the document using spool file. Such change will affect this scenario. Also EMF spool file is not designed for that so we will need to delay PS file header creation until DEVMODE is read.
It will also not work if we ever add support for native print processors / printer drivers.
Why do we need to follow undocumented Windows internals?
I should have written that I don't think we need to be binary compatible. On the other hand there's nothing bad in it if it's not too hard.
Anyway, this were just some notes, I still need to do more testing.
