I have a network printer (Sharp copier) that I am unable to contact from a different subnet . I am on 192.168.100.x. The printer is on 192.168.200.x. I can ping (or remotely connect to) every other device (including switches, desktops, server) on the '200' subnet from the '100' subnet. I have an identical copier on the '200' subnet that I can connect to.
If I am on the '200' subnet, I can contact the printer without any problems. The printer works fine on the subnet.
While I need to be able to connect to the printer across the subnet, contacting the printer from a different subnet is almost secondary. I am more curious in how to troubleshoot this and which device ultimately is responsible for me being unable to contact the printer.
