SYMPTOMS
I want to use the same printer with both Mac OS X and Windows.RESOLUTION
With Parallels Desktop 7 or 8 for Mac, the default Mac OS X printer is automatically used by Windows. You don't need to configure anything.If you make changes to printing options in Mac OS X, the same changes will be applied to Windows after the next time you restart Windows.
Make sure you have Add all Mac printers enabled in virtual machine Configuration ►Hardware ►Print:

Note your default printer in Mac OS Preferences:

In Windows virtual machine under Devices ►Printers you will find the same printer enabled:

Selecting Print option, you will find default printer selected:
