Canon supply their UFRII driver; I would start here
https://www.canon-europe.com/support/consumer_products/products/printers/laser/i-sensys_lbp6030.aspx?type=drivers&language=EN&os=Linux%20(64-bit) and click to download and SAVE what is linux-UFRIILT-drv-v140_uken.tar.gz

open a terminal;
copy the commands below; line by line;
paste each line into the terminal; and hit the ENTER key after each paste

cd Downloads
tar -zxvf linux-UFRIILT-drv-v140_uken.tar.gz
cd linux-UFRIILT-drv-v140_uken

then one runs the install script that should set things up

sudo ./install.sh

you can check as you go: so if you do cd Downloads then if you do ls that is asking to LIST what is in the Downloads directory; so if you see linux-UFRIILT-drv-v140_uken.tar.gz listed there, then go on to command 2) where you unpack it with the tar command; linux is very logical; if it says it can't see it or find it; well, it ain't there ...
