I have a HP 7310 printer that I can’t get to work with my Apple Mac?

I just bought a HP 7310 all in one printer. I loaded the enclosed software and followed all of the enclosed instructions, but the printer won’t print. I unistalled and reinstalled the software sseveral times, all to no avail. It still doesn’t work.
I tried a test to prove that the printer is communicating with the Mac. I pressed the scan button on the printer and the scan DOES appear on the PC. So I know they’re talking to each other. But it doesn’t want to print anything. There is a “start job and stop job” feature on the Mac, which can be accessed, but that window isn’t always available, why I don’t know. When I do see it, I always press “start job” but it doesn’t seem to help. The printer still won’t start.

So here I sit with a brand new printer that won’t print. Please note, I’m a complete novice, so any answer will have to lead me by hand as to how to resolve this problem.

Thanks for all your time and thoughts.
