I neglected to mention in my post about installing the Airport Express with a 3rd-Party router, (a Netgear WGR614, in my case), that I still couldn’t print wirelessly with the device. My HP PSC-750 All-in-One isn’t supported… it makes sense that you wouldn’t be able to scan wirelessly, but why couldn’t I print?
Well, after a few more hours of searching, I finally found a solution, courtesy William Boddie in the Apple discussions:
When queried for a printer, I selected “edit printer list” from the scroll down menu, clicked on “add” under the printer setup utility-> went to IP Printer -> Printer type “Rendezvous” -> Printer Address scrolled to “HP PSC 900 series” -> Printer Model “HP” ->model “HP PSC 950 Footmatic” -> press “add.”
It worked, however the AX is easily the most frustrating Apple product I’ve encountered… let’s hope that HP’s partnership with Apple to co-brand an HP iPod, will spurn HP to write better OS X printer drivers. My landlord is an architect, and he’s mad that his $2500 plotter was rendered useless with his upgrade to 10.3…
UPDATE… I neglected to mention that I am not using the bloated and shoddy drivers provided by HP.
I would instead recommend the HPIJS Open-source drivers. These drivers allows printing “over any available connection such as USB, AppleTalk, TCP/IP (via LPD and IPP), HP JetDirect, and shared windows printers via SAMBA”. And, you don’t have to install the useless extra HP applications, which are included with the driver package.
