It’s a DC-DC converter that works with 9–24v power adapters. The power connector is a 2.1mm barrel jack, same as Arduino, and the printer connections support both 5-pin and 2x3-pin JST connectors.
I teach workshops with thermal printers, make a lot of art with thermal printers, help other folks make stuff with thermal printers, and it is really very hard to find power supplies good enough to work well with thermal printers!
2.1mm barrel jack power input (just like Arduino) 9–24v.
A screw terminal adapter for the barrel jack (use any power adapter that doesn't already have a 2.1mm tip).
7v power output (adjustable!) for your printer.
Works with both 5-pin and 2x 3-pin JST connector printers.
Everything is broken out to a 5-pin female jumper header for easy hook-up: GND; serial RX and TX; DTR (for 5-pin printers); printer VH (same 7v powering the printer)
