|Well, I have yet to do more than give Windows 7 a cursory glance so I can't help you with issues with system settings in it.|
Since you changed nothing, the issue has to be software or hardware. At this point, I would suggest uninstalling, then reinstalling the printer on your computer. If that doesn't fix the issue, you might want to ask about this over in the Windows 7 forum
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
