I upgraded to Mac OS Sierra and now I can not read the DVD that came with the printer or find a downloadable driver on HP's website to get the printer working on Mac OS Sierra. Any suggestions? I do have a Windows partition and I can print from Windows, but I want to print on the Mac OS side as that is where I am 98% of the time. Windows partition is just for one flight simulation program I use once in awhile. It's the wireless printer that we use to print from all our iPad's too. It's working for them but not for printing on the Mac OS side. Any ideas?
