HP LaserJet 1020 Ubuntu 10.04 Lucid Lynx

Same story as always; updating system breaks printing with CUPS. Not sure why, but seems like when using foomatic, no firmware is uploaded to printer.

Remove printer from cups.
Install hplip:

sudo apt-get install hplip hplip-data hplip-gui
sudo hp-setup
sudo hp-plugin

If “sudo hp-plugin” fails, look for hplip-3.10.9.run in /root, and run it with “sudo /root/hplip-3.10.9.run”. After it completes, check that you’ve got firmware files in /usr/share/hplip/data/firmware. Then run hp-firmware:

sudo hp-firmware

If successful, you should now here the printer fires up.
