How do I fix printing and scanning problems using Mac OS X (10.4, 10.5, and 10.6)?
If you have trouble printing or scanning, deleting and re-adding your printer and/or resetting the printing system is often an effective solution: • From the Apple menu choose System Preferences. • In the System Preferences window, click Print & Fax. • In the list of printers on the left side of the window, select the wireless printer in question and click the minus sign at the bottom of the list • Click the plus sign to re-add the printer. • In the Add Printer window, select your printer, and click Add. If you still have trouble communicating with the printer, repeat this process, replacing the third step with: > Right (control) click anywhere in the printer list and choose Reset Printing System.
