Q: Not able to add a new IP-printer

Hi,
I wanted to add a new IP-printer. I know it`s IP address and what else is needed to make it work. But when ever I click "Add", I get this error message:

=An error occured while trying to add the selected printer. Client-error-request-value-too-long=

It`s a LW 12/640, the system is 10.4.11.
I know, that I could run this printer with AppleTalk too. But even adding it by using AppleTalk, I get the same error message.

Hope you can "read" my explanation. Please help.
