How to set working Canon LBP-810 on newest Ubuntu 18.04? Trvehere is no official driver for 64bit linux system thanks
It actually appears that someone reverse engineered the protocol used which lead to the capt driver.
There are instructions here for ubuntu 14.04, but you can definitely compile it from source. The git repo for it is located here and it should be fairly self explanatory to install with the instructions in INSTALL.git and the INSTALL file.
