It sounds to me as if you're trying to port a non-Macintosh program to the
Mac, without having learned much about the software architecture of the
Mac.   You get points for bravery but I'm not surprised that you're getting
some big surprises.

The bad news is that label printing is a very specialized application, and
the existing architecture for printing just doesn't handle it very well.  To
make printing work the way you would like it to would mean a reimplementation
of all of Apple's drivers, and Apple hasn't considered that a high enough
priority.

The good news, though you may not like it much, is that the way printing
works on a Mac DOES make optimal use of the equipment for a very large and
important class of applications, namely the ones that print documents in the
form of pages.  The printing architecture is what supports the WYSIWYG
paradigm that is central to the Mac's design.  It isn't that Apple said
"let's screw the label-printing applications," it's label printing was not
as important as WYSIWYG page images and there were some conflicts between
the two.  The problem could be solved, but so far, as I've said, it hasn't
been a high priority.
