Install Presto (3rd party app that enables you to print from your apple mobile device to virtually any printer on your network).
Login to the computer or server that your printers are connected to
Go to: http://www.collobos.com
Download and install “Presto”
Presto automatically finds your printers and makes them available to your Apple devices. This in turn makes them available to Pick’n Pack.
Note: The computer that is connected to your printer must be on the same network as the wireless devices you are using for Pick’n Pack

Scroll to the right and touch the Print icon.
