Firmware And Character Generators; 10.1 Machine Firmware - Olivetti PR2 E Service Manual

1.10 FIRMWARE AND CHARACTER GENERATORS
1.10.1 MACHINE FIRMWARE
Separate from the character generator and character set, the printer management firmware is
independently managed during the uploading operations so that all access to the character area for
modification is rendered more flexible and immediate.
The printer's basic memory is provided by a 1 MB Flash EPROM. The management FW, the character
generators and character sets reside in this memory and can be replaced on-line.
Asecond Flash EPROM (optional) of the same capacity and capable of hosting complex character sets
and considerable macro and logo volumes, can be installed on the main board.
The machine firmware includes the following emulations:
Olivetti environment: STD 12/14 controlled protocol with the PR2 E native environment, PR40+ and
PR2845 emulation. IBM Proprinter II and Proprinter X24 industry-standard emulation.
IBM environment: 9068 protocol emulation covering also the model 4722. IBM Proprinter II and
Proprinter X24 industry-standard emulation.
Wincor-Nixdof environment: SNI 491 5 protocol emulation covering also the models 4905. EPSON
LQ 2550 industry-standard emulation.
