The Dot Matrix Synth is a software project I completed in 2003 for the Epson LQ-500 dot matrix printer to transform the printer into a synthesizer. Even older printers like this Epson have a computer built into them, and for this project I wrote new firmware for this printer. The printer-synth makes sound by using the noisy dot matrix print head, and different tones are created by driving the print head at different frequencies. Several versions of the Dot Matrix Synth were made -- one for live performance with a button control box, one for playing back sequences, and one for installation in a gallery that also prints out images.

The Dot Matrix Synth has been exhibited previously at transitio mx in Mexico City, The New Museum of Contemporary Art (New York), Rum46 Gallery in Denmark for the readme software art festival, and some other venues in New York.

This zip file includes the project source code, plus technical information and tools for programming the Epson LQ-500 printer.











The printer played manually using the button interface (with argeggiator): printer_arp.mp3 (1.7MB)

Quicktime movie from a gallery installation: movie


Three recordings of the printer using a version of my software that plays sequences using the print head, paper roller motor, and error beeper:

printer2.mp3 (400K)

printer3.mp3 (400K)


A song by Tree Wave that uses the Dot Matrix Synth and other vintage computer gear:

A sample of an early version of the printer synthesizer where a makeshift mellotron was created using cassette tape and parts:
