I've browsed these forums and found others that had similar but slightly different problems than mine so I hope you guys can help me. I'm trying to connect my leopard macbook to a Canon Pixma MP210 that his hooked up to an XP machine. Sharing is enabled in XP on the printer, and I can successfully add the printer to the mac in system preferences. I've downloaded the proper drivers from Canon's website and selected them for the printer. The problem is that when I try to execute a print job, the print queue comes up and hangs on status "printing." Also, on the XP machine, the print queue recognizes a job is being requested but the status hangs on "spooling." The document never actually prints. Finally after a couple minutes, the print queue in the mac has an error stating: "Error Number : 311 Printer is in use or an error has occurred. If an error has occurred, eliminate the cause of the error." I know that I'm close so any extra help would be greatly appreciated!
