+Troubleshooting:
+Problems with a network-attached printer can have numerous causes. Make sure that your device has a proper IP address.
+Often you can check the IP address by triggering the self-test of the device. As a next step try to send text
+manually to the device. You could use for example:
+
+::
+    echo "OK\n" | nc IPADDRESS 9100
+    # the port number is often 9100
+
+As a last resort try to reset the interface of the printer. This should be described in its manual.
