Comment 37 for bug 217215

On Jaunty (with all updates) the firmware files for the HP printers which need a firmware file get automatically loaded when one sets up these printers with system-config-printer which makes the printer immediately working. The firmware gets download as part of the HPLIP plugin, so you need HPLIP to be able to use the files out of the box (by uncompressing, moving/linking, and renaming you could use them also with foo2zjs). Please try it out.
