One of the most commonly returned pieces of equipment due to ‘defect’ or frustration is the Canon LBP600p Laser Printer. Time and again, we have people call unable to set up the device, assuming that the units are failing due to the fact that after configuring, they cannot print to the device. In most (if not all) cases, the device has been set up improperly; a quick look at the manual provides the key step missed.
While the Canon device does show up in the Add Printer window, selecting that device in 10.6.x and earlier will not properly address the machine. The Canon LBP6000 uses a modified CUPS driver; should you miss this step during setup, you will not be able to use the device.
In the Add Printer window, in the lower right of the box, you’ll see a button that says “More Printers.” When the new box appears, the item CANON USB (CUPS CAPT) will appear in the list. Select that device, click on Add, and you’ll have completed the necessary final step to use the printer.
Should you have properly configured the Canon in Leopard or Snow Leopard, then later upgrade your computer to Lion, you’ll need to upgrade the printer driver for proper functionality. Canon offers a new driver that can be found here.
Before installing the new Lion device driver, you’ll need to remove the old driver from your computer. To do this, you’ll want to trash the CAPT folder located at Library > Printers > Canon. You’ll be able to add the device back normally after installation of the new driver at this point.
