How do I find out which Canon flatbed scanners are supported in Ubuntu 12.04?
Specifically I need to know if the Canon LiDE 110 is supported?
You can check the Ubuntu HardwareSupport wiki page. You find a list of Canon scanners there, but the one you mentioned is not listed there - which does not automatically mean that it wouldn't run, though.
On this (German) weblog I read that Ubuntu supports Canon LiDE 110 since 11.04 - so it should run.
