The CorelDRAW  6 Power MacIntosh  version 6.0.1 update may not respect page setup when
printing a page size, other than 8.5 by 11, to PostScript printers. A new fix is available from our FTP
site located at FTP.COREL.COM/PUB/CORELDRW MAC/CORELDRAW MAC/

The following  workaround is currently available: 

Before printing your illustration, click Document Layout, and change the paper size to Landscape. As
a result, when print, you will view a window which prompts you to adjust paper orientation.  Adjust
your printer settings, and CorelDRAW 6 for Power MacIntosh will print accurately.
