I've got about 8 w98 hosts on a tcp/ip connected network. I've read of similar problems but they are not quite the same.
When I print the printer sets itself offline with an 'unknown problem'. If I set it online again it prints the documents but the printer is grayed out in printers. After a bit it comes back.
I don't think it can be any of the connections because it works when I put the printer back online. This happens on all the attached hosts.
