Understanding the Printer Startup Sequence

30
When you switch on the printer, it will go through a sequence of
steps in which it determines what settings should be set and what
application (if any) should be started. Users that run Fingerprint
firmware on their PD42 are given more options and more control
over the printer's startup behavior.
Printer Startup Sequence (Fingerprint)
1 Check for firmware binary file on CompactFlash card. If
found, upgrade.
2 Check for firmware binary file on USB mass storage device. If
found, upgrade.
Note: The printer will install the firmware stored on the
CompactFlash card even if it is older than the version
currently loaded on the printer.
3 Check if printhead is lifted and button is pressed. If so, go to
Extended Testmode, otherwise continue startup with step 3.
4 Check for the presence of a startup file (AUTOEXEC.BAT),
first on CompactFlash, then on "c/". If found, run the startup
file.
5 Check to see if button is pressed. If so, go to Testmode.
6 Continue power-up. Check APPLICATION file in "c/:" for
program file name. If found, run. If empty, go to idle state.
This means you can control the printer's behavior after startup in
a variety of ways: you can create an autoexec.bat file and save it
on a memory card or in the printer's permanent memory (device
"c/"), you can write an application and store the link to it in the
APPLICATION file, or you can choose to enter Testmode.
It is recommended to start custom applications by writing the
name of the desired program ("ProgramName.PRG") in the
APPLICATION file in "c/".
