Here are the steps to set up a printer for the first time:
Launch System Preferences, click the Printers & Scanners icon.
You can open System Preferences from the app menu, or launch it from the Applications folder, Dock, or Launchpad.
If your printer isn’t in the list at this point, click the + button at the bottom of the Printers list and either select it from the list of nearby printers or choose Add Other Printer or Scanner.
Select the printer you want selected by default when you print documents from the Default Printer pop-up menu .
Select the default paper size you want to use with this printer from the Default Paper Size menu (usually us Letter if you live in the United States).
That’s all there is to it. Close System Preferences, and you’re ready to print your first document! Before you do, however, make sure you have the document set up to look just the way you want it to look printed.
NOTE: Some printers around campus are setup to print Duplex by default. For example, the Matthews Copier is set to print on both sides of every page.
