Printing to printer on different subnet & router

[BBL]

Hi,

 

Have a computer on one subnet trying to print to printer on another subnet, but "printer is not responding" when print job is sent.

 

The set up is:

 

Router on 192.168.10.0/24 with connected printer using 192.168.10.49

The router is connected to a second Router's WAN port, and that second router is providing 192.168.20.0/22, which has a computer connected to it 192.168.20.50

 

OS X Computer 192.168.20.50 can ping Xerox Printer 192.168.10.49, but can't actually print to it.

 

Attempting to use IIP printing protocol, since Bonjour is no good over subnets.

 

If computer can get ping response from printer, why can't it print to it?

Drivers ?

Not something daft like port 9100 being blocked by the router / firewall?

Check your Routing rules

 

Check your smoothwall isn't blocking the ports.

On smoothwall try opening all port (very temporarily just whilst you test it) or if you want to be safe unplug your Internet connection whilst you test.
