Note before: The display model depends on the printer make and model, so use Google for finding details (e.g., the I2C slave address and the registers used for transmitting texts or clearing the display area) for a specific LCD model.
In our junk box, I found a damaged laser printer Lexmark T610 from which I extracted an Optrex DMC 50777 LCD. This LCD was connected by a simple 5-pin terminal. The pins of a similar LCD (DMC 50641) are described in an article of the Arduino forum.
|1||EIRQ (interrupt pin, not used)|
|3||SCK (serial clock, connected to the Arduino SCL port - Duemilanove: A5)|
|5||SDA (serial data, connected to the Arduino SDA port - Duemilanove: A4)|
