A user can use the socat command to interact with a USB printer connected to the USB port of a Digi device.
Below you can find an example of the socat command, which starts a service on port TCP 9100 and pass a print task to the USB device.
Configuration>System>Scheduled tasks>Custom scripts>
socat -u TCP-LISTEN:9100,fork,reuseaddr OPEN:/dev/usb/lp0
Since communication will be achieved by the IP address of the router a custom firewall rule must be added:
Configuration>Firewall>Custom rules
iptables -I INPUT -p tcp --dport 9100 -j ACCEPT
