We are using epos JavaScript 2.9.0 to connect and print receipts via our webapp from Android devices. But we are getting only connection_timeout error all the time. Sometimes though it works and is very unstable. It works fine from the connected pc .

Here is my code:

var ePosDev = new epson.ePOSDevice();
ePosDev.connect('IP address', 'PORT', callback_connect);

callback_connect's resultConnect variable always return CONNECTION_TIMEOUT

Is there any specific browser in which you want to run the webapp or it's open? – mehta-rohan Oct 25 '18 at 06:34
