Your IT staffer would look over the IP plan, traceroute to the printer and sort it out. You didn't share details so I can't comment where the failure occured.

I'm having a strange problem. The other day we lost TCP printing on our entire network. Most of our printers use HP Jetdirect cards. We cannot ping any of them, but we can ping computers just fine. We have a Windows based workgroup. All printers have static IPs. We have a DHCP server, and it looks fine, too.
I'm sorry if this is not enough info, but I am not sure what info would be useful.
