The thing to do next is to “reset the printing system.” That gives you a fresh start, and in my experience, resetting the printing system ALWAYS solves the problem, allowing the printer software to be downloaded successfully from Apple. Never, that is, unless you know what to do next. Usually the failure happens when getting the software from Apple: everything seems to be proceeding apace when all of a sudden, during the download, a message pops up saying something about the software not being available, and to “Please try again later.” Try later all you want, but once you see that message it is NEVER going to work.
Apple long ago tired of waiting for printer manufacturers to provide software compatible with each new version of OS X, so they started doing it themselves, and on the whole this has been a good thing for Mac users. So if you too would like to be using OS X on a multitouch monitor, I can personally recommend both the Touch Base OS X UPDD +. Rather, the instructions say, get the software from Apple, and indeed that is excellent advice.
Many printers from Epson, Canon and Hewlett-Packard come with instructions to NOT install the software that comes with them on CDs.
