Does this dot matrix printer count as a project?

I didn't mean to make it easy to take out of context

I love the sounds it makes so much

#

perfect printer sounds

I plan to get my upgraded version working and boxed up. I will have to adjust the homing offset in the code, but for now I'll set it to like 1 step so the code doesn't crap out, then try to move 65536 steps or more

I know nothing about dot matrix printers.
Are you using an existing printer and modifying it, or is this something brand-new?

I use two stepper motors, the paper moving thing is from a broken miniature shuttle dot impact printer, one of the steppers is bought, the other is from a 3d printer, and I use mechanical parts from that very same 3d printer. The original printhead was the one from the mini printer, but the printhead was divided by 6 to get one pin. Now I will use a 9 pin printhead from an Epson TM-U220 receipt printer, but I will still use just one of the pins to print.

#

I really hope it'll work

#

I hope so too! At the very least, it looks cool 😄
Please do share an update if you have it

I might film the final version

#

If it even happens

#

Here's a photo of the hopefully final printer. The photo was taken before I painted over the overly ink fingerprinted parts

#

It grew to around 1.5x to 2x the original size

#

that's still pretty good for something hand-made

dawn pecan Jun 19, 2025, 1:34 PM

#

If it works it works

#

There are some issues with it still, but it might be the Arduino code

#

The issue is that there's a 1 to 3 pixel misalignment between the lines

Here's a heavily cut down and quality reduced video to fit under 10MB

Cool!

There is some ghosting on the print, and that is due to me putting way too much ink into the ribbon

I just thought. How hard would it be to turn my printer into a musical instrument?

#

I would like to have it act like Midi Desaster's MIDI printer, but one channel and no velocity adjustment

#

Or, I could just make the printer go through 800 pixels per line, and send ones and zeros according to the notes and durations

#

Have you seen thing where they turn 3d printers into musical instruments?

#

Not just the beeper, but like, the actual rails and motors
