When you install or upgrade your all-in-one printer software, the all-in-one printer might not be the default printer if you have other printers or document writers installed. You would need to manually select your all-in-one printer each time you want to print to it.

WINDOWS XP OS
- Select Start > Settings > Printers and Faxes.
- Right-click your all-in-one printer.
- Select Set as Default Printer.
WINDOWS VISTA OS
- Select Start > Settings > Printers.
- Right-click your all-in-one printer.
- Select Set as Default Printer.
WINDOWS 7 OS
- Select Start > Control Panel > Devices and Printers.
- Right click your all-in-one printer.
- Select Set as Default Printer.
MAC OS X
- In the APPLE menu, select System Preferences.
