I have been running the same application on XP and win 7. The printouts on win 7 are not as sharp as in the XP , the colors are not as stronge, some of the lines disappear. I am using the same printer and same printer resolution. Tried differnet options in the printer but didn't manage to get to high enough resolution. Thanks, Iditdeveloper

More than likely, it's a driver issue. Check the manufacturer's web site for Windows 7 drivers for the printer. SC Tom -There's no such thing as TMI when asking for tech support.

Also it would be a good idea to double-check your printer's settings, they may be at default or different than the settings in XP.
