Each dot is produced by a tiny metal rod, also called a "wire" or "pin", which is driven forward by the power of a tiny electromagnet or solenoid, either directly or through small levers (pawls). Facing the ribbon and the paper is a small guide plate pierced with holes to serve as guides for the pins. This plate may be made of hard plastic or an artificial jewel such as sapphire or ruby.
Vimeo user MIDIDesaster rigged up an old dot matrix printer to crank out the track, and with some painstaking file editing, ended up with a highly unorthodox — yet just about note-perfect — rendition of the song that hogged the top of the charts during the summer of 1982. Spun off from the ‘Rocky III’ soundtrack, it went down as the second-biggest single of the year, behind only Olivia Newton-John’s ‘Physical.’
has several other musical examples of their printer in action, including the Duke Nukem theme, Hysteria by Muse (one of our favorites), and even the Wallace and Gromit theme!
It’s a similar project to this printer synth we shared almost 9 years ago! Stick around to get pumped up with Eye of the Tiger! But if you’re wearing headphones… turn the volume down
The conventional old dot matrix printer was hardly good at anything, printing included. It was, however pretty dedicated to making loud sounds. It is this quality of the printer that has been harvested, of course with a bit of modifications, to actually create music rather than random sounds. So here we have it, a dot matrix printer playing several fairly complex songs and themes.
