Printer was accidentally unplugged, when I plugged it in, I changed several prit cartridges than did the alignment scan which did not work first time but then was OK. When I tried to print from my Mac, the printer is no longer connected. I did get message on printer that it had been disconnected wrong.
I tried connecting to Mac again but this fails. What can I do to correct this problem. Also it is a HOP deskjet 3520 wireless printer and will no longer work with another computer in another room that had previously worked. Still works with IPad in same house.
