After having updated to LMDE UP3, my HP LaserJet 1320 stopped printing. I deleted it and try to install it again, but now it was impossible to autodetect.
I found some iformation in web forums pointing either to a bug in CUPS or in the kernel (http://www.cups.org/str.php?L3884+Qversion:1.5). Someone suggested to install hplip as a workaround. I did so, and now it's OK. But this bug or upgrade problem made a lot of headache.
