Unable to print in color on new imac
I am unable to print in color. I have a printer HP8720. I have tried everything including deleting and reinstalling the printer software. There seems to be no option available to chose black and white or color. I spent an hour on the telephone with Apple Support who were unable to solve the problem and suggested I go into store where I purchased it which was IQ in Guernsey. Helpful as they were they were not able to solve the problem! Help!!
interestingly I can print in color from my iPhone 13 straight to the printer but my IMAC will only print in black and white.
iMac 27″, macOS 10.13
