after years of proper working with linux mint 17, 18 and 19, when I switched to Mint 20 my HP deskjet 3520 became very very very slow...
text-only pages are ok, but any other type (even text but with borders, or frames, pictures, graphs, drawings) shows this behaviour:
- the file is sent almost immediately to the printer
- the printer feeds the paper sheet
- at this point, the printer process the first "row", then stops for a minute or so
- then moves to the second line, stops again
- and so on
I tried to remove the printer and to make a new setup, removed cups and reinstalled, I tried both with the system printer management console and the hplip gui... no matter what, the behaviour is the same
If I boot the system in the old mint19, averything works fine
do you have any idea about how to troubleshoot this issue?
thanks
