We have a Roland VersaCamm SP-300i. It will frequently loose its network connection. This of course interrupts jobs going through and it stops printing. If we disconnect it from the network and use a crossover cable from the Versaworks PC directly to the printer, everything works fine. Good ping test. If we switch it back to the LAN we get bad ping tests. Anyone have an idea why this might be the case? We don't seem to have any network cable problems at that switch and everything else on there works fine. Thanks in advance!
