Thank you for your answer T6.
Searching for other driver package for Linux I found the Gutenprint project page. The list of supported printers counts the Canon MG4100, wich should work for my printer too. But since the Gutenprint package is already installed on my system and I can find a lot of other Canon models from the Gotenprint list when adding a new printer, I find it strange that the MG4100 is not listed when installing.
But actually the newest version of Gutenprint is 5.2.9, the version in the repos is 5.2.7, so since it's a new printer it might have been added later. On the Gutenprint homepage it is possible to download the newest package as a .tar package.
I have installed alien, and I,m reading about it now and might give it a shot to convert the .deb driver package.
I,ve been using PCLOS for some years, but I am total newbie when it comes to install anything that is not from the repos or drag and drop.
Do you have any suggestion what I should try now?
