Printer appears and dissapears from printing menu

When printing a PDF using Atril document viewer, I get the following weird behaviour. The needed printer is the one dissapearing (it is a **network** printer, using Line Printer Deamon protocol, *lpd*). Yet, when opening the PDF using a browser, printer is available: This happened since today. I ran sudo apt-get upgrade last week but printed fine after that (here is the list of upgraded packages). Using Xubuntu 22.04.1.
