An All-In-One Serial Printer Playground

One of the peripherals of most desire for a microcomputer-obsessed youth in the 1980s was a printer, probably a dot-matrix device. In the decades since, printers have passed into being almost a piece of discardable junk as cheap inkjets can be found in any garage sale. That’s not to say that there’s not plenty of fun to be had hacking older types though, and there are plenty of small thermal printers out there to play with. [Tanmoydutta] has provided a platform that may help, in the form of an ESP32-C3-based serial printer controller.

On board is a level shifter for the 5 volt printer electronics and all the appropriate connectors for the printer, as well as the ESP and onboard USB interface. It’s a networked print server, but one which is entirely and completely hackable. We think the printer in question is this one sold by Adafruit.

So this board makes easier a whole host of printer-related projects, and should you try it you will no doubt finding yourself ankle-deep in little curly pieces of paper. This printer’s not the only one in town though, don’t forget the cheap Bluetooth printers!
