Print job is not accepted.
I have a new iMac running version Venture 13.4 I have an older printer an HPColor Laserjet MF277dw. I am trying to print by wifi and have printed successfully in the past. All of a sudden in the past week, I can't print. I have tried deleting and adding the printer back in several times and have also restarted the entire system - iMac and printer. I notice that there is a green light after I add the printer back in, but as soon as I print, the light turns yellow and the message is Print job is not accepted. What now?
iMac, OS X 10.11
