Remote printing through VPN

I have installed OpenVPN on Raspberry Pi 4 without any incident. DDNS is configured on the ISP router, Port 1194 for raspberry pi (192.168.1.170) is forwarded to second router and on the second router 1194 is again forwarded to the Raspberry pi. The connection is successfully established between a remote laptop and the VPN server. The VPN server (Raspberry Pi) is part of a LAN. Lets name this LAN N1. In this N1 there are 3 network printers (.61, .62 .64) N1 has few other desktops and Laptops. The problem starts when I connect to the VPN server. From the remote laptop I can ping all the printer
