How to Upload a Dell Printer to my Mac Computer

Connect your Dell printer to your Mac computer. The printer will have a USB cable coming out of the back of it (or included in the box). Connect that cable to an available USB port on your computer.
Open a document, picture, or Web page that could potentially be printed on your Mac and then select 'File' from the top menu bar, followed by 'Print.' This will open a printer dialogue box.
Check to see if your printer automatically shows up in the drop-down menu on the screen marked 'Printer.' If so, then your printer does not need to be installed further, and you are ready to print. If not, select 'Add a Printer' from the drop-down menu.
Select your printer from the additional pop-up window that appears and click 'Add.' If you do not see your printer in the list, insert the CD that came included with your printer, install the software, then check to make sure your printer shows up in the drop-down menu.
Attempt to print another page. This time your Dell printer should be in the top drop-down 'Printer' menu.
