Printing across LANs

[derek_bartram]

Hi,

In my home I have two networks (A and B).
The printer is on LAN A along with various other servers - these servers can all ping and use the printer.
Machines on LAN B cannot ping or use the printer, but every other service works normally (e.g. RDP, network shares, FTP, web, etc.).

I have the two LANs assigned to different interfaces on the firewall, with the interfaces each assigned a different IP range.
I have firewall rules in to allow any traffic, of any type, on any port, to be allowed to any target/type/port, set for both LAN A and B.

Both the sources and printer have the correct default gateways set.

Any ideas?

powercycle the printer / update firmware

some models have a terrible networking stack
