What is it
This thing is basically a button that dispenses one sheet of A4 paper when pressed. You can press it multiple times to get more sheets. The button is mounted near the laser printer.
The hardware consists of a former elevator button (1st floor) and an ESP8266 (Wemos D1 mini) with the button (active low) on pin D1.
The software can be found on its github page.
To compile and upload it, install platformio, enter the source directory and run the following commands
pio run -t upload pio run -t uploadfs
or install the ESP8266 toolchain in the Arduino IDE and open the .ino file. There is some debug output on the serial port at 115200 bps.

graph paper
Graph paper (dutch: 'ruitjespapier') is dispensed by sending some postscript wrapped in PJL (printer job language). Some postscript examples:
- Jason pratt wrote graphpaper for producing graph paper, written in postscript.
- http://www.trueelena.org/computers/scripts/graph_paper_in_postscript.html
