I was having this problem with a Canon PIXMA MP470 printer (https://www.usa.canon.com/internet/portal/us/home/support/details/printers/support-inkjet-printer/mp-series/pixma-mp470) connected via USB to Ubuntu 16.04.2 LTS. As per https://wiki.ubuntu.com/DebuggingPrintingProblems, I applied the following commands:
$ cancel -a $ lpq MP470-series is ready no entries $ lpadmin -p MP470-series -o usb-unidir-default=true
I hit "Print Test Page" from the Printers settings dialog. The printer test page then printed as expected.
