Welcome to Justanswer.com, my name is ***** ***** I will do my best to assist you.
The most current driver made for that printer was for OS Lion 10.7.. While we can get that download to work, it can be a bit tough at times..
So lets try this.. Connect your printer via usb to your mac. Then go to this page
Select drivers and downloads, select lion 10.7 And then download the Cups driver.. Once downloaded, open it and install it.
Then on your mac go to the printers and scanners window in system preferences. Then click the + sign and add your printer. Once added, try a test print.
Ideally, this should work. But if you run into any issues let me know and if needed I can connect to your mac from here and get this working for you directly.
