+# 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.
+
+## Commands
+
+### Wanted Output:
+    +---------------------+
+    | Dein Passwort:      |
+    | 0123456789          |
+    +---------------------+
+
+### Test Output:
+    echo -e "\r\r+---------------------+\r| Dein Passwort:      |\r| 0123456789          |\r+---------------------+\r\r\r" > /dev/usb/lp1
+
+### Final command:
+
+    #!/bin/sh
+    
+    echo  "\r\r+----------------------+| Dein Passwort lautet || " > /dev/usb/lp1
+    pwgen -N1 10 > /dev/usb/lp1
+    echo "           |+----------------------+\r\r" > /dev/usb/lp1
