2 line LCD display from HP 4100 printer

[JoSSte]

I found a display from a HP printer, and have been wondering if I
could use it for displaying some text for a project.

It's a 2line LCD display with backlight.

The PCB is marked S-11812D, made in japan GCMK-G3X

the only connector is a 20-pin connector with a label marked 0X21088C

anyone got an idea/datasheet or a tip as to where i might get more
info, I'd appreciate it.

20 pins suggests it has a driver IC on board. Try to identify it if you
can, but also look for any of the standard types of 2-line display, it's
probably one of them.

....and a large number of them follow a 'standard' pinout.

What chips are on it?

Search for "Hitachi HD447800", which is the old workhorse standard chip
for such dot-matrix LCD displays, and typically use one of a couple
pinouts.

My NEC printer had one.As did a Toshiba fax machine, and a couple keypad
doohickeys I bought surplus, and at last one junk cell-phone around here
has one.

Look up hitach 44780 LCD displays though they used 16 pins (14 pins
for LCD and 2 for backlight)
