I have an iMac and was using a wireless HP printer no problem. Yesterday, I upgraded to the all in one and modem/router from Rogers so I have had to create a new home network. So the iMac says my HP printer is the default but it can't find it. I am guessing this is because I need to add the printer to the new network as well. Any advice on how to get this setup? I have tried every angle I can think of but no joy... I'm still a newbie on Mac (won't be able to use that excuse much longer I guess).
