I had tried bidirecional 0 and 1. None worked.
Should'n netstat listen on LAN IP (192.168.15.252)? Or could it be 0.0.0.0 since it's passed directly to USB?

I don't know what to try.

keep it simple for now:

config p910nd
        option device        /dev/usb/lp0
        option port          0
        option bidirectional 1
        option enabled       1

Why? Am I missing part of the story here?
OpenWrt defaults to accepting incoming connections from LAN, you shouldn't need a firewall rules for p910nd to work.

Thank's. I will try and let you know. This one was generated by Luci.

I didn't got it, but decided to follow this guide, since i got no sucess. https://openwrt.org/docs/guide-user/services/print_server/p910nd.server

I changed the /etc/config/p910nd and did a reboot.
After reboot, turned on printer and it printed 2 Windows test page. I don't understand this after a reboot. If i send a job i still got error. Tried to reboot the router but got no print anymore.
Tried removing the firewall rule, turned service off and makes no difference.

Still no solution but i found something interesting. I will try later.
