In Windows 98/ME/2000, click Start > Settings > Printers.
In Windows XP, click Start > Printers & Faxes.
This will launch the Printers & Faxes dialogue box. All the print drivers loaded on the PC will be listed. The one with a little black circle with a white check on it is the default printer resident on your workstation.
 
Please note that this may not necessarily be the same as your "default" printer in GOLD. It is also possible to have a default printer in GOLD and have no default print drivers loaded on your PC.
