Q: I recently updated from O.S. 10.6 to Mountain Lion and had additional memory installed.  Now I can't get my wireless printer to print wirelessly.  I went to Airport utilities as suggested above, but it says it can't locate any airport base station.  Help!

I just updated from OS 10.6 to Mountain Lion.  My HPC4780 wireless all-in-one will not print wirelessly, even though it indicates it is getting a wireless signal.  I followd the "airport base station firmware updates" suggestions, but my computer can't detect an airport base station, even though I am looking at it, and the light is green like it is supposed to be.  The printer works if I connect it, but won't print wirelessly.  Any ideas?  I am trying to learn Mountain Lion's ins and outs.
