Many, many thanks for the change. I reportet this already at 2005-10-15 in bug #3599.
But nobody seemd to take care about this problem. I think this brings the whole thing much furter.

After consulting with some local Linux consultants, we have concluded
that Corel Draw does not print under WINE because it detects the printer
as Postscript, converts the file to Postscript, and sends the file to
CUPS, which then converts the file to Postscript, again, and sends it to
the printer which prints garbage.
The consultant found a way to make a couple changes to WINE files and
force CUPS to pass it through and it prints beautifully on a color printer.
Here are his changes:

My question; Is there a way to force CUPS to pass through a Postscript
file from Corel Draw and allowing other programs running under WINE to
use the CUPS drivers as normal? (The consultants changes force the pass
through on all programs running under WINE).
Possible other solution; Is there a way to force Corel Draw to send a
format which can be converted or pass through CUPS to the printer?
