Diancaibao needs a printer to print a test page. When the printer is turned off, press and hold the paper feed key and turn on the switch, and you will see the ip address on the test paper of the printer. Just add the ip address to the port and apply it.
The last step of ordering treasure is to set the printer binding in the ordering software. You need to contact the software manufacturer for specific guidance, because every catering software is different.
Diancaibao protocol port:
If Diancaibao compares the IP address to a house, the port is the door of the house. A real house has only a few doors, but an IP address can have as many as 65536 ports (2 16)! Ports are marked with port numbers, which are only integers between 0 and 65535 (2 16- 1).
On the Internet, hosts send and receive data packets through TCP/ip protocol. Each data packet is routed in the Internet according to the IP address of its destination host, and the data packet is successfully transmitted to the destination host.
Most operating systems support multiple programs (processes) running at the same time, so which process should the destination host send the received packets to? Obviously, this problem needs to be solved, so the port mechanism is introduced.
