Hi, I have just bought a brand new iMac and this is my first ever mac. Downstairs we have a Windows XP PC that has a canon iP4500 printer connected to it. I am trying to connect to it on my mac over the wireless network in our house. The printer is set up to be shared and works over the network as we can print from our Windows Vista Laptop wirelessly. Our wireless network is set up over a Belkin router. On my mac I am managing to see files on the computer that the printer is connected to. On that PC I can see shared folders on my mac. When I go to print something on my mac i get the error "Error Number : 311 Printer is in use or an error has occured. If an error has occured eliminate the cause of the error." [See below - Thumbnail 1] And on the windows pc in the print queue window the print job shows up as a "Remote Downlevel Document" with a file size of 0kb and nothing gets printed. I have visited canons website and tried all OS X drivers including the CUPS version and NON-CUPS version. PLEASE HELP!!! I do not know what I am doing wrong in my printer setup.
