BETA, Skip this version if you use 1 printer :)
Multi-Printer support and button functionality
BUGS:
- After configuring 2nd printer, 1st one will disconnect. Workaround: just reboot device and it will work.
- When idle, device will show white screen after some time and toggle with clock every minute. I forgot to add idle clock for 2nd printer
Final version most probably around next weekend: 22.03 :)
