Here is an example script to move a users currently mapped printers to a new
print server as defined in a PRINTERS.INI file.

The PriMapState UDF for this example is located here and is a more updated version then this example.

Code:
; Set our options
Break On

; Set $CurrentIP to Global so other functions can use it's value
GLOBAL $CurrentIP

; Assign the returned value of the GetCurrentIP() UDF to $CurrentIP
$CurrentIP=GetCurrentIP()
ResetPrinters()
