I am having the exact same problem. I have the HP OfficeJet 5610xi all-in-one. It worked fine under 10.5, but broke with 10.6. It should be the "HP Officejet 5600 series" driver.
I'm getting the same error where it wants to download via software update, but then I get the message:
The software is currently unavailable.
You can check for the software later by choosing Software Update from the Apple menu.
If I go manually into the "add printer" interface, both the Officejet 5600 series "usb multifunction" is shown as well as the "Officejet 5600 series [XXXXX] (fax)." If I load the FAX one, I can scan. But printing sends the print job into etherzone. It just never prints, though the print queue will look like the job successfully printer. weird! electing the 5600 series just plain does NOT print.
Should we wait a few days? I noticed HP says that support is supposed to be within Snow Leopard. As shown here:
grr. I really can't deal without printing. It's not like this printer is ancient or anything. It's only a couple years old.
p.s. if you go to
http://support.apple.com/kb/HT3669 you will see that our printers are not listed! The pulldown says the following:
If your printer or scanner does not appear in the list below, visit the device manufacturer's web site or contact the manufacturer to find out if software is available for Mac OS X v10.6. If software for your printer is not available and your printer supports a common printer language such as PostScript or PCL, you may be able to perform basic printing functions using the Generic PostScript or PCL drivers available from the "Print Using" pop-up menu while adding a printer.
Well, I couldn't get the above to work.
