Printing between two networks

helio58 · Mar 21, 2025

Hi,
Problem printing.
I have two networks.
Internet router lan ip 192.168.1.0/24 and another router connect to the first router ip 192.168.1.33
with lan 192.168.2.0/24.
I have a cups printer in the second lan 192.168.2.23:631
users in the 192.168.2.0 lan have no problems printing.
Question how can I make the printer discoverable in the 192.168.1.0 lan?
Both routers running Asuswrt-Merlin
Thanks

You would likely use LAN > Route to setup a route. See this if you haven't already:

Thanks thats the setup i m using.
The problem is discovering printers and sonos devices cannot be accessed between networks.
Is just that part that is not working.
File sharing works both ways.
Thanks

That's expected. Device discovery doesn't normally work across subnets without additional "helper" software.

Sorry, no idea. Discovery of IPP printers is not something I've ever wanted to do. Personally I've always used reserved IP addresses and host names for printers so there's no need to "discover" them. From what I've read CUPS would use DNS-SD for device discovery.

Again, for Sonos devices I've no idea as I've never used them. I've read in these forums that they can be troublesome to discover even within their own subnet. IIRC they use mDNS for discovery. So that would probably mean you'd have to use the router's avahi-daemon with the enable-reflector=yes option set (see other forum discussions regarding that.).
