The printer works with PC, but doesn't work with my device.Select "Serial", this should solve the problem. There you can see the " I/F mode", where you can select: Serial / Parallel / Auto. in the following menu you can setup other printer parameters (just after the language setup). Power the printer up and hold the " Font" button. Problem may be in switching from serial to parallel communication on the printer. The printer sometimes works, sometimes doesn't.Other parameters can be left set to default. &T: Serial Line Timeout 0 - Automatic mode.S: Send to IP and U: Port - IP adress a port of PortBox1.I: Address and J: Port - IP adress a port of PortBox2.S: Send to IP and U: Port - IP adress and port of PortBox2.I: Address and J: Port - IP adress and port of PortBox1.It might be enough to set one portbox as a TCP client and the other as the TCP master, but we prefer to use the active (Client / Server) mode. To use the scheme on the picture, you need to set both PortBoxes to communicate with each other and to create a virtual serial port through the ethernet network. For example you can connect the printer to your central alarm unit or stock reporting. This paragraph describes how to use two PortBoxes to connect the printer to any serial device via the ethernet network. The print-ready state is reported by the DTR signal on pin 20, the full funcion can be achieved by a 3-wire connection, you just need to test the serial line speed (9600 Bd by default). The printer does not support the HW handshake, the CTS input signal is ignored, the RTS output is activated permanently.
