The problem is solved in Ubuntu Hardy Heron 8.04. Simply install HPLIP-Toolbox: Applications - Add/Remove.... Or hplip-gui in Synaptic, if you prefer.
When you start HPLIP Toolbox (in System - Preferences), it starts a sequence that allows you to download and install the missing firmware. Just say "OK" to each proposition that the toolbox puts before you. Have fun with your beautiful printer! :-)
