Extended System-Level Command Functions

backward compatibility only, limited in range (28-228).

the scaleable font engine. Available memory dependent upon model; see Appendix
K. (For non-display models see the <STX>KS command.)
(SE) SOP Emulation – This command enables the <STX>O and <STX>f print
positioning commands to allow backward compatibility with label formats designed
for other printers.

as the last command in an <STX>Kc command string, saves the effective printer
configuration to a file in Flash memory with a .dcm file extension.

emitter of the Media Sensor.
