I have been printing just fine to many media on my Z3100 and just recently upgraded to Snow Leopard on my mac. Seemingly found the correct driver because the HP print utility connects just fine to the printer and everything can be managed from there just fine.
However, when I send a file to print the print dialogue box shows the file spooling to the printer, but this message shows up in the status box:
No %%BoundingBox: comment in header!
The file disappears from the print queue and never prints.
I would say reinstall all the new HP software and try again.http://h10088.www1.hp.com/cda/gap/display/...3183_4041_100__
With me it all seems to work.
Also i think the software update from Apple will provide you with the HP software.
PS my situation:
HP Z3100--44 inch
I have APS installed 1.41
- that now also works
