A thermal printer (seems to be the SP-100 Statement Printer) was optionally available for this device.

 * Specs are per thiggins' review..
 * Seems to be sold by Handlink as the WSG-5000 - whose ticket printers look mightily similar to those used by some later D-Link hotspot gateways, probably including the D-Link DSA-3200

Default settings are per ZyXEL's manual.
