Hi,

try to change Local network to 192.168.0.1

Also, what do you mean by "see my printer"? Is this printer being broadcasted over the net (mdns) and you want to find it on the list? If that's the case then it won't work like this. 

That broadcast is not being transferred between the networks (LAN/VPN).

Can you ping the printer's IP while you are connected to vpn?

I did not know how else to describe it. This is the printer connection dialog box in Flashprint:

When I connect with the vpn, I need to be able to find the printer so I can connect to it. Right now I'm not able to find it manually or automatically?

  @3DScanSTL 

have you tried with 0.1 in OpenVpN server config as mentioned before?

Can you ping that device while connected via vpn?

Auto Scan won't work imo. It has to be configured with IP as you showed.
