For a production environment you may set the printer to use a static IP so it is always the same IP address. Alternatively, setup your router/DHCP server to always assign the same IP address to the printer based on the printer's MAC address. Router configuration tools/web interfaces may refer to this as "Static DHCP", "DHCP reservation", or "IP-MAC binding".

Make sure "Allow RAW(Port9100) Printing" is checked.

825 may make a network client connection on Port 9100 to the printer's IP address and send text data to printer. The printer buffers data received until a (form feed) character is received. The CCommClient class in lib825ev may be used for TCP/IP communications as a client CCommClient
