Adding Printers and Copiers in Managed Software Center
To add printers, first open Managed Software Center (located in the Application folder):
Once it loads, you will see Printers listed as a category on the right hand side. Click on the Printers category, and from there you just click Install on the printer/copier you want and then check for updates and apply just like you would if you wanted to install some of the optional software. Then click on the Updates tab and click Update All, and the printer/copier will be installed on your machine. Below is an illustration of the process.
