So I have been using my C4780 for over a year. I was sent Snow Leopard with my Mac Book when I ordered it but had a product that was no supported by snow leopard so I stuck with Leopard for the year. I recently upgraded to snow leopard and the printer now takes at least 30 minutes to process and print when connected to USB. This is terrible! I uninstalled the software upgrade from the website and reinstalled it and it there was no change. Can someone help? I have not found this problem posted for the USB, only the wireless printing.

Hey there. Lets try reseting the printing system first:
Go to System Preferences > Print & Scan
- Right (or control) click in the rectangle listing your printers and select Reset Printing System.
WARNING - this will delete ALL of your printers!
- Select the plus sign to re-add a printer. Select the Default tab on the top of the window. Look for the printer, select it and wait until the "Add" button becomes available. Click it.
Let me know if this helps.
