I have an HP LaserJet 1320, and Lubuntu 20.04 on an old Macmini. Since I installed Lubuntu 18 packagewise over Ubuntu upgraded from 16, I have been encountering a printer error. ** I have since completely wiped and reinstalled Lubuntu, using only default printing software.**

Sometimes, particularly when copying text from webpages into LibreOffice, my printer prints these two pages instead of whatever was requested.

error pages

Since wiping the entire OS, I think it’s been working better, but sometimes this still happens. Occasionally, other things will happen such as the page having the right borders and tables and stuff, but it looks like between libreoffice and the printer there was an encoding mistake, and several characters are replaced with gibberish symbols.

Why is this happening now, and how can I fix it? I am almost certain it is because of ghost characters, since if I paste to and print from featherpad, the problem disappears. But why was it working before and not currently?

…Is there a way I can remove these ghost characters without losing special formatting?

Edit: as per comment, I installed hplip and it’s GUI, but I am still encountering the problem. HPLIP was apparently involved in the job (see image). print status I even exported to PDF and printed from the HPLIP GUI directly, but with the same error. What should I do?

    Does this answer your question? How to install HPLIP on my Ubuntu to support my HP printer and/or scanner? – N0rbert May 22 at 15:42
  • @N0rbert Maybe so. Thanks, I’ll check it out. – TheLabCat May 22 at 15:45

  • It's not clear to me what you're actually running. You mention Lubuntu 18 (no such release as yy format releases are snap only and Lubuntu is deb based so do you mean 18.04) which to me is a concern. The release notices said things can break so re-install was the only supported method to upgrade from 18.04 to 20.04. The 16 & 18 refs just confuse me (and are potential troubles due to desktop change). – guiverc May 22 at 23:51
  • @guiverc I am sorry that was so confusing. What I was trying to say was that I originally had Ubuntu 16, then I upgraded to Ubuntu 18, installed lubuntu-desktop via apt, upgraded to lubuntu 20, then wiped and fresh installed lubuntu 20. – TheLabCat May 23 at 0:05
