Lonkero & SeaLeopard,

Thanks for your thoughts.
I corrected the additional quote at $PrinterName"
and now I'll try do discover what this means:

Script error : invalid method/function call: missing required parameter 3 !
mapprinter($PRServer,$PrinterName)

Unfortunatelly no more info on UDF topic MapPrinter from MasterOfDesaster.

Thx again for your time.
