I have just purchased the DeskJet,  and I am VERY satisfied with the machine.
I am using the HPDJ driver (public domain) and it works quite well.
I would be surprised if the DJ+ offered much of a speed increase on the
Mac, since even on my (deskjet) system,  the printer has to wait for the
serial link to gather data before it prints, so what is the difference if
it has to wait, then print, or if the DJ+ has to wait, then print REALLY
fast?

ps This problem could be solved with a high speed serial - parallel
converter.
