1720 dn error message when 2nd prints via network, no konfiguration possible

    Hi,

I installed the 1720dn first on a PC with paralellport and everything was fine. Than I configuered it for network and also everything was fine.

But than I tried to connect another PC to the printer via network or via sharing but there pops up a error message when I try to change the konfiguration to for example print duplex:

"Funktionsadresse 0x34a05a9 hat eine Schutzverletzung verursacht. (Ausnahmecode 0x0000005) Die Eigenschaften werden möglicherweise nicht angezeigt." - sorry I cant translate. The strange thing is that first PC can print without any problems and also the second one can print but cant change the settings because of the error.

Waiting for help,
