I'm a new user of OpenWRT. At the moment I have configured two TP-Links and I really like the flexibility of OpenWrt.
Now I'm configuring the MR3220 for using of the HP M1120n printer and scanner. I have build an image with necessary usb support, and moved overlay to microsd card. The version is 17.01.5. I installed p910nd and sane for printing and scanning. Scanning is working well, but for a couple of days I could not setup the printing. I have tried with and without firewall rules - just "error of printing" on windows machine.
Printer recognized
root@LEDE:~# dmesg | grep printer
