Socket Communication - SATO CL4NX Programming Reference Manual

6.10 Socket Communication

2 types of connection can be used in the socket server function of TCP/IP; 2 port connection that uses Port 1024 for
receiving print data and
Port 1025 for printer status return, and 1 port connection that uses Port 9100
for print data receiving and printer status return.
When using Port 9100, the printer returns only status return data and the printer operation setting request data.
Using both 2 port connection and 1 port connection at the same time is not available.
Each socket cannot connect to multiple sessions at the same time.
LPR and FTP are available for sending print data in addition to socket. During connecting LPR or FTP, connecting to
print data port (Port 1024 or Port 9100) with socket communication is not available.
2 ports connection with Port 1025 and Port 9100 is not available.
