The default printer string consists of the printer name, driver, and port as shown in these examples:
DefaultPrinter = "HP LaserJet 4,WINSPOOL,\\Mynet\Myprint"
DefaultPrinter = "Epson AP-4000,WINSPOOL,LPT1:"
To force InfoConnect to always use the default printer specified in the Windows Control Panel, set this property to an empty string.
