In the top right corner of your Mac, there is a magnifying glass symbol.
Clicking that will launch Spotlight. Start typing "System Preferences" and launch the top result (double-click or hit return/enter).
Select the Printers & Scanners preference pane (highlighted below)
In the Printers & Scanners Preference Pane, click on the "+" button in the bottom left.
This will bring up the dialogue to add a printer. Start typing the name of the printer in the top right of that dialogue. The list of available printers will shorten as you type. Once you see the one you want, click on it once to highlight it. Information below will update, but you'll have to choose a driver from the dropdown. Click on the dropdown and Select "Select Software…"
From there you can type the model number of your printer into the search field until it your printer driver comes up. Select it, click OK, click Add and you should have a printer. :)
