Loadable Firmware/Character
Generators
The firmware and character generators of the passbook and document printer
are stored in a programmable memory with FLASH technology. The function for
loading this memory is implemented by a resident program (bootstrap loader).
The load function is activated either by control sequences in one of the printer
emulations or by simultaneously pressing the key combination USER 2 and
STOP when the printer is switched on.
The printer cannot be operated when the load mode is running.
– The menu settings are not available.
– The interface functionality is limited to the control functions for the bootstrap
loader.
The loader program can be exited by
– Switching off the printer.
– Entering a control sequence after the firmware and the character generator
have been loaded successfully.
The functionality is available on the physical interface RS 232, Centronics
interface card, and on the ’LAN interface’.
