Welcome to Justanswer.com, my name is ***** ***** I will do my best to assist you.
How is your printer connected to your mac, via a USB cord, or networked?
Also, what version of mac osx do you have, you can check as follows. Click the apple sign at the top left of your screen, then click about this mac. And then where it says version, send that to me as a reply.
My apologies for the delay in getting back to you. By the time you had responded I was on my mid day break.
Did you still need help with this issue? If so, would you like me to temporarily connect to your mac from here and solve the issue directly, on screen?
