In the comments about the Photo Smart 7520 on Amazon I read about people 
(or maybe it was just one guy) who claimed he needed to repeated plug 
and unplug the power cord to get it to work.  What you describe is 
probably that problem.

Another guy on Amazon said that his printer mysteriously turned itself 
off one day.

Thanks for the info!  And the great clarification.  I certainly don't 
want to buy a printer that's going to throw problems at me all the time. 
  Sometimes I feel like the public has been turned into a bunch of beta 
testers for some of this new technology.
