A Strange Display Gives Up Its Secrets

Providing a display for a project in 2020 is something of a done deal. Standard interfaces and off-the-shelf libraries for easily available and cheap modules mean that the hardest choice you’ll have to make about a display will probably relate to its colour. Three decades ago though this was not …read more

Reinking Dot Matrix Printer Ribbons Because It’s Fun, Okay

Ink! No matter the printer you’ve got, whether it be inkjet, laser or otherwise, it’s the consumables that will send you broke. At times, the cost of Hewlett-Packard black ink has exceeded the price per volume of human blood, and shareholders around the world have rejoiced.

As a retrocomputing reprobate, …read more

Relive The Dot Matrix Glory Days With Your 3D Printer

With the cost of 3D printers dropping rapidly, we’ve started to see a trend of hackers re-purposing them for various tasks. It makes perfect sense; with the hotend and extruder turned off (or removed entirely), you’ve got a machine that can move a tool around in two or three dimensions …read more

Restoring A Forgotten Dot-Matrix Printer

Dot matrix printers are the dinosaurs that won’t go extinct. They are not unlike a typewriter with the type bars behind the ink ribbon replaced by a row of metal pins controlled by solenoids, each pin being capable of printing a single pixel. At their best they could deliver a surprising level of quality, but their sound once heard is not forgotten, because it was extremely LOUD.

[Wpqrek] bought an old dot-matrix printer, a Commodore MPS 803. Sadly it didn’t live up to the dot-matrix reputation for reliability in that it didn’t work, some of its pins weren’t moving, so …read more

Full Color Dot Matrix Is The Art We Need

Fans of 80s-era computer printing technology are few and far between, but Apple’s ImageWriter II was a beast of a printer. This tractor feed dot-matrix printer is nigh-indestructible. The print quality was actually pretty great. It was loud as hell, which is a mark of quality electromechanical components. It could do color, and color dot-matrix art on tractor feed paper is the aesthetic we need. If you’re not convinced yet, you can also take off the perforations from tractor feed paper and make a cool little paper snake.

[Dandu] isn’t one to let things like serial printers and obsolete color …read more

Dymo Rides Again With This Dot-Matrix Label Embosser

For a five-year-old future Hackaday scribe, there could be no greater day than that on which a Dymo label maker appeared in the house. With its spinny daisy-wheel to choose a character and its squeezy handle to emboss the letter into the plastic tape, there would follow a period of going nuts kerchunking out misspelled labels and slapping them on everything. Plus the things look like space guns, so there would have been a lot of pew-pewing too.

This Dymo dot-matrix label maker bears no resemblance to our long-lost label blaster, but it’s pretty cool in its own right. The …read more
