The program ScanGear MP2 installs the printer driver, so you only need to run it once, which is probably why it doesn't get put it in the menu. The link given by Rich seems to tell you all you need to install the printer.

I am new to Linux Forum and using Linux Mint 19.3 Cinnamon and have just installed a Canon Pixma TR8550 printer. I have installed Scangearmp2 from Software Manager and launched it. However it doesn't appear in the Graphics list. I find I have to launch it by opening Software Manager then Graphics and type in scangearmp2 in the question block. This opens the install block and from there I launch the scangearmp2 successfully see attachment. Is there any simpler way to do this?

Hi, and welcome to the forum.

I've not used Canon Printers so have no direct knowledge but printing /scanning issues in general can be problematic.  This is not a fault with Linux, more that the manufacturers do not always provide Linux compatible drivers for all of their products.  That said, look here -

to see if that helps?  Alternativey, if all you need to do is scan - in Mint, go to Menu/Graphics/Simple Scan and see if that works.  And make sure your printer is switched on when you open the app.

I had the impression when I joined that there was a Minecraft forum for Linux (Ubuntu)

I cannot find it, so, is there one?
