It sounds more like a printer/driver configuration problem. Anyway, the KDE print
dialog lets you control what's controllable for the selected underlying print
system. With LPR, you can't control the page size when sending a print job, but
it's possible with CUPS (properties button).
However when printing from Qt, you also have to tell the QPrinter object which
page size you're using (to know where to print). When using CUPS, the QPrinter
object is synchronized with the possible page sizes described in the PPD file, so
when you select a page size, the QPrinter knows it, and the PS generated will
also contains page selection code for the printer. With LPR, if you use the
properties button, you will still be able to select a page size, but that's ONLY
for the QPrinter object, so if you select a different page size than the one used
by the printer (which is not controllable, it's fixed on printer installation), you will
probably have problems.

But in your case, if even when printing a PS file (with lpr command-line utility), you
get this overlapping problem, I would say that you driver is mis-configured, or
you're using a non-appropriate driver. And I'm afraid the current kdeprint stuff
won't change anything (except if the page size selection for CUPS plugin solve
your problem). The KDE print stuff is not a print system by itself, it's a common
and flexible GUI interface for various existing print systems. If you can't print
correctly from the command-line utility (lpr), then you'll also have problems using
the KDE print stuff.

If you want, I can try to help you to solve your problem, but maybe we could switch
to private mails.

Bye.
Michael.
