Mapping Examples
Once the PGL files and GPIO mapping table have been downloaded to, and
the special serial connector is installed on the printer, the printer prints label_1
when the – key is pressed, label_2 when the Feed key is pressed, and
label_3 when the + key is pressed. It does a form feed when the Down key is
pressed. The Menu and Enter keys are non-functional.

This works without the GPIO board installed in the printer; all it requires is the
specially wired connector at the serial port. As indicated, it could also be
combined with the Protected Printer example (see page 51). A connector
placed at the GPIO port could disable all this and allow a service engineer to
work on the printer without restrictions.
