wine users - Nov 2008 - PowerBuilder 10-based app: Printing issue

Hi to all,
Last year I ask for help here, for a PB-based application issue, and the good
folks here pointed me to a solution :-) Now I got another problem.

Part of the app consists in print invoices. That function works in Windows, but
in Wine I got an screwed printout.

Just for experimental purposes, I installed the "CUPS-PDF" package, to
get the PDF view of the invoice, and the PDF looks good (if you don't know
what CUPS-PDF is, it lets you create a "virtual printer" in CUPS,
which takes your printjob and transform it to a PDF file, much like the
"Export to PDF" function of OpenOffice.org).

I put two PDFs in anyhs.dontexist.net, showing a "good invoice",
printed with CUPS-PDF; and a "bad invoice", printed to a real printer.

I ran the app with WINEDEBUG using the "print", "printui"
and "winspool" channels, but I didn't find anything that seems an
error or bug, except for this:

fixme:psdrv:PSDRV_ExtEscape QUERYESCSUPPORT(25) - not supported.

I tried other programs, M$ Office and Firefox 3, and they can print fine. 

Even my problematic PB app has some functions to create and print reports, and
they print fine as well. It's just the "invoices" part the one
which messes up its printjob.

And the debug switches I tried doesn't give me any clue about what's
missing; neither "err" nor "fixme". But I can do some
debugging again and post the results here, if someone asks to do it.
