Canon i950 printer error 311
Hello, I just hooked my Canon 950s printer to my MacBook Pro. Documents look like they're going to print and spool to the printer window. The light on the printer flashes orange and nothing prints - not even a test page.

The Error 311 indicates a communication error between the Mac and the printer. Therefore I would start your repair by trashing all of the Canon files.
The first step is to disconnect the USB cable between the printer and the Mac.
The next step is to delete the current printer queue for the i950. Open Print & Fax, select the i950 in the list and click the minus ( - ) button to remove the queue. You can now exit Print & Fax.
The third step is to remove the Canon files. These are located in HD > Library > Printer > Canon > BJPrinter. Select all the files inside this folder and trash them. Then empty the Trash and restart the Mac.
With the Mac restarted, you can now run the installer for the 10.6 driver you downloaded from the Canon web site. (if you haven't downloaded it yet, do so now.)
Once the driver has been installed you can connect the i950 USB cable to the Mac again and open Print & Fax. If the install has worked, the printer should automatically appear in the Printers list (note that this can take several seconds). If the printer does not appear, click + to add and select the Default view. The i950 should appear in this view. Select it and click Add. You may get a prompt stating the printer is already installed. If so, cancel this install and try printing with the new i950 queue.
If the error message still occurs, then I would try another USB cable. They have been known to cause the 311 error.
