I have the same problem. Using Mavericks gives the result "The printer is not responding"
Vuescan doesn't connect to the scanner either.
HP Photosmart C6280, MacbookPro, OSX Mavericks.
I have on the same machine also a partion with Snow Leopard. When I startup with Snow Leopard I can print and scan without a problem. But I like to do that with Mavericks as well.
Is there anyone who has a clue why I can't print?
I deleted and added the printer in the system prefences, that didn't help.
