Emulation and Character Sets
To be compatible with all the various standards, a printer must be extremely
flexible. This printer is a front-runner in terms of versatility. Its resident
firmware and optional memory cards give you the possibility of operating in
several different emulation environments.
The default command code set for the standard printer version is the Hewlett-
Packard PCL level III Extended (Printer Command Language) - see Appendix
E for an overview of the command codes. Two optional emulations are also
available on memory card: IBM Proprinter X24 and EPSON LQ 850 (contact
your dealer for details). Depending on the applications you intended to use, you
can choose the emulation which best suits your needs (see Appendix C "Printer
Controlling").
NOTE: Once an optional emulation card has been inserted and selected, only
the command code set contained in it will be used. To return to the resident
emulation, the printer MUST be switched off, the optional card removed and
the printer switched on again.
Character Sets
A character set is a group of characters and symbols concerning a language or
a specific technical language (mathematical or scientific). The character sets
include punctuation signs and figures. In the PC and printer world, a character
set contains up to 255 different "characters". Of these 255 characters, the
codes from 0 to 127 are standardised and contain the so-called ASCII codes.
This is the American character set, which excludes all European national
characters and symbols as well as the semi-graphic signs.
The assignment of codes between 128 and 255 varies from country to country,
from hardware to hardware, from operating system to operating system and
often even from application software to application software. Before selecting a
particular set, you must read your operating system / software application
documentation carefully.
