I could not find an appropriate driver for the printer. Tried other Canon drivers; a generic Postscript and generic PCL5/6 but when I send a print job, the printer wakes up but does not print. The same happens when using wireless or USB connection. Other Canon printers work just fine.
MX920 series IJ Printer Driver Ver. 3.90 for Linux (debian Packagearchive).
MX920 series ScanGear MP Ver. 2.10 for Linux (debian Packagearchive)
Install the driver from Canon (ver 3.90). Oddly, it shows up on its Asia site, but not on its US site. This worked for me on Ubuntu 14.04 Trusty.
