We just recently upgraded 2 macs to new yosemite OS and now we are having trouble printing to our HP Designjet 5000ps. Printing directly causing prints to come B&W only and same thing is happening if we are trying to print through older (10.4) OS. We got newest available hp driver. Previous os 10.9.5 was printing fine via bonjour. Any idea how to make it work?
Thank you
