Hi Thomas and Henrik
Thomas is correct: My mentioned solution is not the really wanted one !
Henrik, did you consider an Ethernet Print Server Solution ?
A NETgear Print Server PS113 is connected to an 8-port Router which connects all our PC's with each others and the WWW.
2 printers are connected currently:
1) a B/W Canon BJ-230
2) a COLOR Canon BJc-6100.
The 3rd printer port is free and used for guest or test printers !
