My elderly neighbor who is an accomplished engineer and has been using Linux for ages recently upgraded his distro. I think he is using Ubuntu or Fedora. Now whenever he prints pages every line of text has a line through it.
He has been able to verify that it is not his printer. He has tried a Live CD as well and is having the same issue. When he goes back to the old version things print fine.
He surmises it is some sort of diagnostic feature in CUPS or some other part of the printing subsystem that is improperly turned on by default.
Has anyone seen this before? I am not a Linux expert, but I would like to help him out.
Thanks. I gave him this suggestion and the one from others about using the manufacturer’s proprietary drivers.
Also depending on the architecture on the computer, this might be the only possible solution. I have a samsung m2020 series printer connected to a Pi to share it on the local network. Samsung Unified Driver does not work on armhf as it is only compiled for x86/x64, but splix can be compiled on armhf and it actually supports my printer
