Problem in ethernet printer

[kavin]

Hi,
        The following code will query the our zebra printer for error.

memset(port_monitor_buffer,0,sizeof(port_monitor_buffer));
retn =write(device_fd,"\033E 1\r",5);
retn =read(device_fd,port_monitor_buffer,sizeof(port_monitor_buffer));

       so i put this code in backend the same code in USB backend works fine even in Ethernet i can able to feed the command to the printer but cant able to get the response from printer thats my problem.

        please help me.
