# Password-Printer

``printer.sh``
This script prints out a random passoword on a thermal printer upon button press.


## Device

We use a Card Start 8010 thermal printer. With the USB adaptor, you can simply send text via echo to the /dev/usb/lp1 device. It is printed if the line is full (24 characters) or when a "\r" sequence is sent.
