Adobe pdf won't print in black and white only, on HP Officejet Pro 8610
I'm on a Mac, using Yosemite and at the same time as I upgraded to Yosemite, I switched from HP Officejet Pro 8600 to 8610.
Ever since I made those switches, I can't get the Officejet to print Adobe Reader documents using only the black cartridge. All other apps print in black only, no problem.
FYI: I have no choice but to use Adobe Reader for a particular report, as it won't open in Preview. So I have to solve this issue because it's wasting color ink.
HP said it was an Apple issue, because all other apps print in black and white, no problem.
When I called Apple, they said to go to Adobe, since there aren't any settings that can be changed on my iMac computer.
Does anybody know how to solve this issue?
