A:AnswerYes, it is compatible. Used it with Mojave. But, user beware! Ours stopped connecting to our network after 44 days. HP was less than helpful. We are now stuck with a printer we can't use and money we can't get back.
A:AnswerI believe so, as long as you are running Win 7 or greater it should work. I have this printer working on Windows 10, MacOS and android 9.0. everything got installed automatically being a wifi printer.
