Hello @DantSu,

I tried to implement the TCP Printing to Network Printer however getting exception com.dantsu.escposprinter.exceptions.EscPosConnectionException: Unable to connect to TCP device.

Can you please suggest me any solutions.
Thank you.

Code

private void print() {
new Thread(new Runnable() {
public void run() {
try {
EscPosPrinter printer = new EscPosPrinter(new TcpConnection("192.168.1.5", 9100, 15), 203, 48f, 32);
printer.printFormattedText(

I am afraid no one is replying on my issue. Is it visible to all? Or do I need to do anything to make it visible.

It's very urgent !! Please help!!

try pinging ip address before sending print command, that may fix your issue.
