Hi Chainsaw; welcome to the Mint forums
Canon supply drivers for your printer: it is connected by usb cable? Mint uses debian packages so if you go here http://support-asia.canon-asia.com/cont ... 86102.html
and click to download; and select SAVE when asked to choose;
you will be downloading cnijfilter-ip8700series-4.10-1-deb.tar.gz
and it will be saved to your Downloads folder by default;
If you open a terminal: its icon should be about 4-5 icons up from Menu; bottom left; to paste into a terminal, use your mouse and the Menu to Edit on the top line; as the short cut is shift control V which needs 3 fingers!!
so if you paste the commands below into a terminal; having downloaded the file as I suggested above; and after each paste into the terminal, hit the ENTER key ...............
tar -zxvf cnijfilter-ip8700series-4.10-1-deb.tar.gz
watch the screen: it will ask you to confirm a couple of things;
and that should install the driver and you should be able to print
If you copy and paste this command
cngpij -P IP8720USB
into the terminal, it should open a dialogue box to change settings on the printer; if it works; and is helpful; we can guide you to set up a launcher for repeated use
