Selecting your Stylus Scan in the Chooser
After you install the printer software on your Macintosh, you
need to open the Chooser to select your Stylus Scan. You have to
choose the Stylus Scan the first time you use it or whenever you
want to switch to another printer. Your Macintosh always prints
using the last printer selected.
1. Choose Chooser from the Apple menu. Click the SS2500
icon, and the port your Stylus Scan is connected to.
2. Click the Background Printing radio button to turn
background printing on or off.
