To add a school printer, click on the Self Service icon which may be found in your Dock (the bar at potentially the bottom of the screen with a lot of icons in a row) or navigate to the Applications folder and launch SAES Self Service.
Once Self Service is launched, you can attempt to search for the printer you want to add by using the search bar in the top right of the window. For example all lower school printers begin with "L - " or you could search "Library" for the library printer.
If you cannot find the printer by searching, you can click "Printers" under Categories on the right hand side.
From there, just find the printer you want to add and click "Install". Self Service will do everything for you.
If the printer you want to add is not listed in Self Service please email support@saes.org.
