I installed Parallels 4 and the newest Mac OS upgrade but can't print from PC programs (all works fine on the Mac side). The Canon MX860 worked on the PC side previously. On the PC side, I downloaded the newest driver, installed the Canon software and the printer is recognized as the default printer in the Control Panel (connected as LPT1) and each of my PC programs. Yet I continuously get the message that the Printer is not responding. I tried to configure in Parallels the USB connection but it just says nothing is connected no matter how many times I plug and unplug the printer. Ideas?
