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.
I had the same problem, the end result will be like talisman or cursed text.
I fixed the problem by switching from generic printer driver to the property one (unfortunately I had to install it from their site by downloading it using the browser like a windows scrub 🤢).
My printer is a old HP printer and distro is fedroa 38 (gnome)
Hope this helps ❤️
