For a long time now I have used a USB-connected Canon LPB3000 mono laser printer. It suits my needs perfectly and I like it, and I want to continue to use it. Problem is that for the last few OSX upgrades I have had to manually remove the driver files, restart OSX, empty the Trash, use a .dmg file from a Canon web site to re-install the driver and then, finally, go to System Preferences to add the printer. This has worked for the last few upgrades, but what a PITA! Since El Capitan things have gone pear-shaped. I noticed that there was a newer version of the CAPT driver at Canon (Mac_CAPT_V385_uk_EN.dmg, dated Sept 2015) so I used that and followed the procedure which has worked in the past, but now when I try to add the printer via System Preferences all I see is “No printers are available”. I have re-set the printer system and re-installed OSX to try to beat the problem. Nothing works. Is there anyone out there who has managed to get their old Canon laser printer to work with El Capitan (10.11.1)? How did you do it? Can anyone else offer some helpful advice, PLEASE!!
