How can I connect to other system on different Interface

I have my router configure with three interfaces. One is for WAN (internet) and two for LAN which one is wireless and the other is wired. Everybody on wired LAN can shared printer connected to a system on wired but system on the wireless cannot use that printer.

Is there anyway I can connect from the wireless interface to the wired interface?

You’re not giving a heck of a lot of details, but I’m guessing you’re running Windows and both ports are routed. Either bridge them into the same broadcast domain so NetBIOS can resolve names, or use a WINS server, or use Active Directory.
