I have red so many webpages, writing so many commands into the terminal now that Im quite fed up actually. Nothing works....Regretting installing 20.04 distro. Trying to install Canon printer TS3151 driver. Sorry to say this, but on Windows 10 it took me 5 seconds without reading thru a bunch of webpages. I thaught ubuntu had come further than this. So my question is: Has anybody the real answer to this??? Had luck with it? How do I do it?
