PTX has its own GPIO configuration methods

PTX Font cache is configured in 
PRINTER CONTROL

HexDump Mode is available in 
DIAGNOSTICS
 Menu
<STX>T Printhead Dot Pattern Test Label
<STX>Z Print Configuration and Dot Pattern Labels
DIAGNOSTICS -> Printer Tests
<STX>J Set Pause for each label
<STX>p Controlled Pause
These commands can be supported by using PAA to filter out the 
commands, and have GPIO put the printer in Single Label Mode. 
A panel-key can then be assigned by GPIO to either print the next 
label (for 
<STX>J
), or disable pause mode again (for 
<STX>p
).
Partially Supported Commands
<STX>t Test DRAM Memory Module
<STX>w Test FLASH Module
This command tests the DRAM / Flash, and reports back to the 
host. DGL always reports ‘OK’ status.
