Thermal printer CITIZEN MLT-288 and Arduino (Medium)

Hello! It's my first seriuos project I've made a long time ago. It is simply thermal mechanism pulled out from old cash register.

I based on https://github.com/3zuli/thermalPrinter/blob/master/thermalPrinter/thermalPrinter.ino

All connections you will find here:

All pins marked "VH" connect to 5V, "GND" to ground. Other pins to any microcontroller.

The whole mechanism is a shift register. You put data frame -> latch -> strobe 1-6 -> move the paper with a stepper and repeat it until the end of the data.
