Instalation of the printer (HP Deskjet) via the switch was easy. After both computers had installed the Druckersoftwar, the switch did not work, he let not be switched with the buttons between PCs. But first had to be intaliert the driver for the switch. According Bedienugsanleitung should it insert a CD that was not included.
After I had the software downloaded and installed on the manufacturing side funkitionierte also the switch! After a restart of both PCs can switch the control of the PCs.
Something unständlich but now it works. Instalationszeit printer and switch drivers insgsammt lasted about 20 to 30 minutes.
