Indeed the drivers are not so easy to find. Upon searching for your model in the Support section of the main website, you will not get any results and instead you have to perform a deep search.
I have managed to narrow down the results by searching for specific terms and came up with a number of drivers for your printer model. You can click on this link and download the drivers for your Mac version.
After you download the package, double click it and it will mount and you will see a new folder on your Mac desktop. Browse that desktop and start the install application. Then it will ask for your username and password attached to the Mac then the process is automated and you can use your printer to its optimal settings.
