I cannot see anywhere on the HP website where it says that this machine is supported under OS 9.2
Let me rephrase that. I have now found the page on which HP state, very clearly:
Quote
Does not support Mac OS 9, 10.1.5 or earlier, 10.2, 10.2.1, or 10.2.2

Not supported in the Classic Environment
Unquote.
Your chances of finding a driver are virtually nil.

Sorry.
Hope you didn't spend too much on it
