Network printing - Source code

from config import *
g_config_printer = read_config("config/printer.json")
def sendto_printer(amount, id_number):
mysocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

logger.info(label)
try:
# connecting to host
mysocket.connect((g_config_printer["ip"], g_config_printer["port"]))
mysocket.send(label) # using bytes
mysocket.close() # closing connection
except Exception as e:
logger.error( e)
if __name__ == "__main__":
sendto_printer(amount, str(time.time()))

2. Print through serial port

Serial printing -  Source code

import serial
# Designated serial port
serialPort="COM3"
# Specify the baud rate
baudRate=9600
# Open the serial port
ser=serial.Serial(serialPort, baudRate, timeout=3)
CMD = open('.//SerialPrinter.txt')
data = CMD.readline()
# Sending and receiving data
while data:
ser.write(data)
print(data)
data = CMD.readline()
ser.close()
