CON2PRT.exe (Zero Admin Kit)

Connect or disconnect a Printer

All commands issued using this utility will affect only the user currently logged in. Con2prt is therefore ideal for managing NETWORK printer connections when used in a login script.

Syntax 
      CON2PRT /f
      CON2PRT /c \\PrintServer\PrintShare
      CON2PRT /cd \\PrintServer\PrintShare

Key
       /f  - remove all network printer connections
       /c  - connect to \\PrintServer\PrintShare
       /cd - connect to and set PrintShare as the default printer

Several switches can be combined in one command line. So you can remove all connections before adding new ones all in one command, you can only specify one default printer.

For recent versions of Windows Microsoft now recommend the more flexible RUNDLL32 in preference to con2prt.

The freeware utility AdPrintX is very similar to Con2Prt but has additional functionality, including compatibility with Windows 9x systems.
