program and resident fonts are 'good' or 'bad'. Good part numbers are

in the direct-thermal mode (no ribbon).

(see Section 2.3.2, Table 2-3).
Internal − indicates the status of the Printer's internal dip switch located
on the main logic board (see Table 3-1).
Paper − this value indicates when paper is present in the sensor.

These sensors tell the Printer where the start of the label is located. Refer
to the Programmer's Manual when determining which sensing mode to
use.
