I'm using Ubuntu 14.04, installed from scratch, not upgrade.
The only unusual setup I can think of is that my root partition is btrfs.

In my case, the problem is intermittent. Some days everything seems to work as expected.

When it happens, I launch the system-config-printer tool and open the printer's queue dialog. This sends the jobs to the printer.

Thanks for the suggestion. I had already done that.

Same issue on 16.04, x64 fully updated.
Unity desktop.
File /etc/xdg/autostart/indicator-printers.desktop present, content unaltered.
Manually exectuting /usr/lib/x86_64-linux-gnu/indicator-printers/indicator-printers-service fixes issue until reboot.
