Firmware and Character Generators
Basic Emulation
This printer's basic firmware is stored in a 4 MB EPROM mounted on the
main board. It emulates both HP Deskjet 500 and HP Deskjet 500C printers,
with all the relative character generators.
The LJ 110/120 automatically selects between the two emulations depending
on the type of print head installed (monochrome print head: HP Deskjet 500;
color print head: HP Deskjet 500C).
Optional Emulations
EPSON LQ 850 and IBM X 24 are the optional emulations available. Each
emulation contains the relative character sets, and both are stored on a specific
card.
The optional emulations are capable of handling optional memory card fonts.
In order to enhance the graphic fonts of the LQ 850 and X 24 emulations, a
memory extension card that allows DLL (Down Line Loading) management
needs to be installed.
Character Generator
The character generator assigns a specific printable character to each code in
the graphic set.
The first 128 codes in the ISO table (0-127) are standard and represent the
USA ASCII character set. National variants and semigraphic symbols are not
included in this code group.
The allocation of codes from the second ISO character set table (128-255)
differs depending on the country and product.
