Browser Print Software over VPN

I'm unable to use the browser print software over a VPN connection to a networked GX430t. I can ping the printer from the PC connected to the VPN, but the Browser Print settings menu cannot detect the printer.

I can print from Windows to the printer successfully if I install the driver on the PC and the PC prints normally when connected locally (without the VPN).


I'm not sure how the software detects the presence of the printer, but this seems to be what's causing me difficulty.

Hopefully someone can point me in the right direction, thanks!
