When printing under Ubuntu 9.10's default WINE installation, all graphics are mirrored and flipped upside down. Text is printed correctly. So the image:
AB "Regular Text" CD
Would print out:
DC "Regular Text" BA
(where ABCD is a graphical image.)
Printer is a Samsung ML-2010. It prints correctly with native Ubuntu applications.
Is there any sort of configuration in WINE to change how graphics are printed?
