Hello, and thank you for using this service.
Sorry you are having trouble. I will help you now.
Is this printer connected with USB or a network connection?
Thank you for the information. I'm actually going to be away from my desk for awhile, so will opt your question out to the other experts for review.
Hi. My name is***** you for your question and the opportunity to assist. Are you using a dual-band (2.4 Ghz and 5Ghz)
router? I don't know of any 5Ghz wireless printers but almost every recent Mac has 5Ghz capability.
If the Mac is connected to a 5Ghz network and the printer to a 2.4Ghz network, the Mac won't be able to see it.
