Problem With Photosmart C4500 Series After SL Upgrade

Possible Fix for you

I had a similar problem with the C4500 after SL upgrade. My printer window showed an error saying that I needed a software update to use it. But no such thing seemed to exist. And all info out there seemed to suggest that the two should be compatible.

My fix:
1) Go to System Preferences.
2) Go to Print & Fax
3) Under "Printers" at the left, hit the + button
4) You will have the opportunity to pick your same printer, but it will have a slightly different designation. Do that, i.e., pick it, and click on "Add".
5) Then choose it from your list of printers.
6) Then try to print something, and if you have a choice of printers, choose that one with the new designation. Do this just to make sure that it is all linking up. (Mine did.)
7) Then go back to the System Preferences/Print & Fax area and REMOVE the "wrong" printer, i.e., the one with the old designation. You do that by highlighting it (the wrong one) and clicking on the - button below that column.

This cleared up my problem completely.
