How to connect a printer on a different subnet?

Question

System administration

Hello, I'm new to this business, so do not judge strictly. We have a domain with AD. It includes all users of the company. In one office, it was recently necessary to install several additional workplaces, and there were not enough sockets with the Internet. I put a router there, which I connected to a free outlet, and from it I already powered the jobs with the Internet. There is a shared printer that is connected to a computer on the main subnet. All computers that are connected to the router see the printer, but do not install it. Error code 0x00000002 "Windows could not connect the printer" appears.

Answer 1

Put a router in there.

What for? There you need a stupid switch (switch). Switch cable from WAN port to LAN and check.
Disable Firewall in the router. If this is DLINK (he will burn forever in hell), then SPI.
Google gives a bunch of solutions, I would try to remove the drivers.

Answer 2

Turn off the DHCP server on the router, connect the incoming wire to local ports on DLINK, so that all devices are in LAN ports (the router will cease to be a router, it will become a switch).
