Save Millions of Pounds on Ink With a Printer That Taps Out Images Using a Pencil

By Andrew Liszewski on at

Years after it was revealed that HP’s printer ink was more expensive than actual human blood, printing photos at home on an inkjet is still a ripoff. You’re better off having them printed professionally at a photo center, or, by recycling a bunch of old electronics into a home-made printer that uses a tapping pencil in lieu of ink carts.

YouTuber Terrormink upcycled an old scanner, hard drive, and CD-ROM drive with some Meccano parts and an Arduino to run the whole thing. The printer itself isn’t easy on the eyes, but there’s a lovely aesthetic to the pointillist images it creates. What isn’t quite as lovely is the incessant tapping sound that’s more grating than even the loudest of dot-matrix-printers of the ‘80s.
