1. 150ms to 200ms interval is required to close port then open port, if you want to open and close
print data port (Port 1), Status port (Port 2) and send/received port (Port 3). Short interval
setting may cause double connection. Request for double connection occurs when [CONNECT]
request is made to Port (Port1, Port2 or Port3) in addition to the request [CONNECT (Socket
OPEN)] which has already been made to Port (Port1, Port2 or Port3). When printer receives
request for double connection, it sends response of Disconnection (Socket CLOSE) to the
