#WARNING!!!: Make sure a serial TTL printer is used, NEVER CONNECT A SERIAL RS232 TO PI'S GPIO!!! even using a TTL conection, never conect the side #printer Tx pin to Rx GPIO on the pi, the Tx wire is only used for rare cases where the printer returns data to the computer. It’s left unconnected #because the printer works at 5 Volts and the Raspberry Pi at 3.3 Volts… connecting directly to the Rx pin could permanently damage the Raspberry #Pi! (The other direction is safe as-is.).

#  Serial Data Cable Rx TO    Physical pin 8 It's also commonly known as "Serial TX" ttyAMA0.
#  Serial Data Cable Tx  DO NOT CONNECT IT TO THE GPIO RX AS SOME ARE 5 V TTL WILL DAMAGE THE RASPBERRY PI!!!
#  Serial GND from serial printer to any gpio GND could use Physical pin 6,9, 14.

#-----Push buttom and LED.

#Push bottom N.O. to Physical pin 16 switch to GND.
#LED+ Physical pin 12 LED- TO any GND available.
