For my Canon imageRUNNER LBP3460 desktop laser printer, I can happily report that the new "Canon UFR II/UFRII LT Printer Driver & Utilities for Macintosh Version 10.8.1" are compatible with OS X 10.10 and 10.11 (also known as "UFRII v10.8.1 Printer Driver for Mac OS X", January 29, 2016).
Last week I upgraded a Mac mini (Mid 2011) from OS X 10.8.5 to 10.11.3, Once it was El Capitan I could no longer use Canon’s UFR II (“Ultra Fast Rendering II”) printer driver for this printer.
Other similar Canon printers can instead use PostScript 3 as a printing language, but this model LBP3460 does not; it can only use the Canon UFR II Print Controller on the Mac platform, which seems to not be supported in OS X 10.11 El Capitan. (In fact, previously installed UFI II drivers get moved by the El Capitan upgrade into an “Incompatible Software” folder at the root level of a Mac’s hard drive.)
Canon’s own support page for this model doesn’t list any drivers or software for recent Mac OS X versions, at least not as of today: "There is no driver for the OS Version you selected. The driver may be included in your OS or you may not need a driver."
So instead I tried the latest PostScript driver 4.6.1 which is compatible with OS X 10.11, but this wouldn't allow me to control the Paper Source settings correctly.
I fortunately came across a discussion that referenced "UFR II/UFRII LT Printer Driver & Utilities for Macintosh V10.8.1"

Released 01/29/2016 for Intel Mac OS X 10.5 - 10.11.2, the Canon download page for this driver required Flash; so instead I found another page from Canon Australia containing the disk image Mac_UFRII_Ver1081_03.dmg here:

In time I”m sure that Canon will update their Drivers tab for my model to include this driver, but until then it’s good to pass along this discovery.
Also note another change: after installing these new Canon drivers, when you go to “Printers & Scanners” to Add your Canon printer, select IP and then choose Protocol ”Line Printer Daemon - LPD” to add the printer (not “HP Jetdirect - Socket” as with other Canon printers). Also note: when you go to choose which driver to use, the new UFR II driver will have no text after the printer’s name, e.g., just “Canon LBP3460”, not “Canon LBP3460 PS”.
