4. create Pi user (Raspberry Pi Imager does not like to create Pi as default)

5. sudo adduser pi

6. sudo visudo

7. Add pi user to root privilege pi ALL=(ALL:ALL) ALL

8. sudo apt-get install samba cups -y
   8.2 sudo apt install printer-driver-splix install printer driver

9. Backup cupsd.conf sudo cp /etc/cups/cupsd.conf /etc/cups/cupsd.conf_backup

10. sudo nano /etc/cups/cupsd.conf

11. ChangeListen 0.0.0.0:631 in cupsd.conf

12. Add ServerAlias * Allow all
    

13. sudo gpasswd -a pi lpadmin

14. sudo systemctl enable cups

15. sudo systemctl start cups

16. set up printer https:\\<IP-Adress>:631 16.1

2. check if python is installed -> open cmd prompt as admin
3. python --version
4. check if pip is installed
5. pip --verion
6. install esptool see https://tasmota.github.io/docs/Getting-Started/
7. python -m pip install esptool
8. attach USB to serial adapter to ESP32 module and the PC, check in windows device manager which COM port the serial adapter is
9. backup firmware
10. python -m esptool --port COM4 read_flash 0x00000 0x100000 fwbackup2.bin
11. delete flash storage of the ESP32 module
12. python -m esptool --port COM4 erase_flash
13. download tasmota.bin from tasmota website, add to the system32 directory. tasmota32.factory.bin for the first time flash should be used!
14. python -m esptool write_flash 0x0 tasmota32.factory.bin
15. after flash is finished, disconnect ESP32 module. The normal tasmota GUI should appear.
