Connect a Printer to Your Mac with Mountain Lion
You could connect your Mac with OS X Mountain Lion to thousands of printer models, and each one is a little different from the next. In other words, if what you’re about to read doesn’t work with the printer you’re trying to connect, RTFM (Read the Fine Manual). It should tell you how to load your ink or toner cartridges.
That said, here are some very general steps to connect a printer to your Mac:
Connect the printer to your Mac with the cable snugly attached at both ends (printer and Mac).
For your printer to work, you have to somehow connect it to a data source. (Think of your phone — you can’t receive calls without some sort of connector between callers.)
Plug the printer’s AC power cord into a power outlet.
Yup, the regular kind of outlet in the wall; on a power strip; or, best of all, on a UPS (Uninterruptible Power Supply). Some printers require you to plug one end of the AC power cord into the printer; others have the AC power cord attached permanently. The point is that your printer won’t work if it’s not connected to a power source.
Turn on your printer.
Look in the manual if you can’t find the power switch.
If your printer came with software, install it on your Mac, following the instructions that came with the printer.
(Optional) Restart your Mac.
You need to do this only if you had to install software and the Installer told you to restart.
