[1]
Signal directions given relative to the printer.
[2]
If active with no current print job, “WAITING FOR DATA” will be displayed. Specifying a quantity of 9999 while keeping this signal ON will cause non-stop label printing, except in single label “Imaging Mode” which will cause the printer to stop between labels.
[3]
See PRINTER OPTIONS / GPIO PORT.
[4]
Drawing more than 0.5 amps can cause unreliable printer operation.
WARNING: Failure to properly configure the GPIO Port jumper settings may result in damage to the printer and / or applicator.
