I recently had problems with one of my machines after several power outages that my brother was able to get going for me, but now my printer will only work from one machine and I can't get the other two to see or print on the printer. The printer I have is a Canon all in one MP 280. It looks like the sharing is okay on the machine it is connected to, but when I go to printers and faxes it doesn't show up, so I try to add a printer and I get the attached image. It tells me I need a driver then I get another image as attached. I am lost, and this is just one of the two I cannot get to see the printer. I forgot to mention that it was at this time that I added a password to sign on to my machines. Prior to this all happening the printer was accessible from 3 machines, although one I am not using now and am using a notebook in place of that one I took off. But all the machines have the same sign on password.
