Selecting your printer in the Chooser for Macintosh
After you have installed the printer software on your Macintosh, you
need to open the Chooser and select your printer. You must select a
printer the first time you use it or whenever you want to switch to
another printer. Your Macintosh will always print using the last printer
selected.
1. Choose Chooser from the Apple menu. Then click your printer's
icon and the port your printer is connected to.
2. Select the appropriate Background Printing radio button to turn
background printing on or off.
When background printing is on, you can use your Macintosh while
it is preparing a document for printing. In order to use the EPSON
Monitor3 utility to manage print jobs, background printing must be
turned on.
3. Close the Chooser.
