How do I connect my Canon ImageClass 4000 BW printer on Lion?

If this is an MF4xxx series then it needs the latest version of UFR2 driver to support Lion. If you upgraded to Lion from Snow Leopard then there is a chance that the driver is not the latest and the cause of the problem.

If Lion is a new clean installation and you did install the latest UFR2 driver for Lion, then can you confirm which exact model you have and how it is connected to the Mac, for example is it via USB or Ethernet?

Sorry for my confusing reply. I had never heard of the imageCLASS 4000 so that's why I thought it was an MF4000 series. Seems like it was only sold in the USA and quite a number of years ago.

So I checked the Canon USA web site and saw the hqx package you refer to containing the old Adobe PS driver for OS8. I also saw an old version of a PCL and PS driver for Windows.

So working on the assumption that the device does support Postscript you should be able to create a printer queue using the Generic PS driver included with Lion. If this doesn't print or simply prints rubbish then change the printer queue via Options & Supplies > Driver to use the Generic PCL Laser driver.

The queue name could be the cause of this symptom. Some print controllers, like the EFI (Fiery) print controllers that Canon does use on several models, require specific queue names. So if you have configured the print queue to use the LPD protocol and your 4000 is using a Fiery print controller then try a queue name of print (all lower case). Note also that the other IP protocols of IPP or HP Jetdirect do not require a queue name but would require that they are enabled. So you should see if you can print a network configuration page to see what protocols are enabled in the printer.

Not offended but I'm happy to help without payment.
