I have downloaded 2 javascript SDK for Epson printer that supports TM-U220, and both of them won't connect to my printer and won't print. But when I tried to use other SDK such as QZ Tray, it worked, but the QZ Tray must be turned on, I want this to work in android, so I use the javascript SDK from Epson.
The problem is when I use the printer sample that Epson provided in the javascript SDK and input the ip: 192.168.1.98, port: 9100, and device id: local_printer, I got this error :
connected to ePOS Device Service Interface is failed. [ERROR_TIMEOUT]
.
But the printer did a small printing, letter that I can't read, and at the very end of the print : 2http/1.1. And in the console :
OPTIONS https://192.168.1.98/cgi-bin/epos/service.cgi?devid=local_printer&timeout=10000 net::ERR_CONNECTION_REFUSED
and
OPTIONS https://192.168.1.98/cgi-bin/eposDisp/service.cgi?devid=local_display&timeout=10000 net::ERR_CONNECTION_REFUSED
I've also created my own simple code.
This is my first code using epos-2.3.0.js :
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>Print Test</title>
<script type="text/javascript" src="epos-2.3.0.js"></script>

ePosDev.connect(ipAddress, port, callback_connect);

- hey man, I have the same problem, how did you fix it?? and other question, why you use port 9100, in documentation it say that is port 8008 – Daniel Arenas Commented Apr 19, 2017 at 19:43
- @DanielArenas Sorr, I still can't fix it – Michael Reno Pratama Setyawan Commented Apr 26, 2017 at 1:11
- I have the same issue, it prints the same content if connected to port 9100. If somebody knows how to change this please let me know :) – Ee-P Commented Apr 28, 2017 at 18:42
- @MichaelRenoPratamaSetyawan Have you got any solution for the reported issue? Please suggest as we are facing the same issue. – kishan Radadiya Commented Apr 9, 2019 at 13:44

Reset to default 2I was getting the same errors for a new TM-T88VI. Then I saw in the ePOS SDK User's Manual that in order to control a TM printer you need to enable the ePOS-Print setting from within the EpsonNet Config on the printer.
Looking at the manual in order to control a TM-U220 directly (without using a TM Intelligent printer) you'll need to have a UB-E04 or UB-R04 network interface installed. It says you can check which interfaces are installed by printing a status sheet.
From the look of it, this is a Cross Origin HTTP Request issue (CORS). This MDN article explains this: https://developer.mozilla/en-US/docs/Web/HTTP/Access_control_CORS
I am guessing that the IP 92.168.1.98 is the printer IP (which is on the local network). See: http://trendblog/ever-wondered-use-192-168-x-x-ip-addresses-home/ and you can access it via port 9100 as described in your post above.
So since your actual web application is residing on a different IP than the printer IP and the way the web work, CORS is required when you are calling to a different IP / host so to prevent cross site scripting attack.
It's mon sense that if the printer is exposing itself via port 9100, you should have that as part of your URI. That is the reason why http://192.168.1.98:9100/cgi-bin/epos/service.cgi?devid=local_printer&timeout=10000 works and the other one did not.
As for trying to access this via an Android device... the question is does the device is joined to your local network (192.168....) or is it on the Internet? If it is joined to the internet, I don't think you can access the printer which is probably not going to be exposed to the internet (having public IP). As long as they belong to the same network, they should be able to talk. If not, you will need to expose it to the internet (bad idea) or make sure they can see each other (Android connecting to your corporate WIFI and the printer can be reached via the WIFI).
I had the same problem with a TM-T20III. You have to use the utility software from Epson for your printer. In the advanced network settings, there is a menu which call "Filters" and I add the IP address of my POS as accept address.
But When I change the address from http://192.168.1.98/cgi-bin/epos/service.cgi?devid=local_printer&timeout=10000 to http://192.168.1.98:9100/cgi-bin/epos/service.cgi?devid=local_printer&timeout=10000 it printed me this :
Port 9100 is the raw input port of the printer, it seems to print the whole input request without interpreting it. ePOS Service seems to be available on ports 80 / 443.
I was getting the same errors for a new TM-T88VI. Then I saw in the ePOS SDK User's Manual that in order to control a TM printer you need to enable the ePOS-Print setting from within the EpsonNet Config on the printer.
Enabling the ePOS Print Service was the right solution for me. In order to do this, i had to update the firmware of the printer (TM-T88VI). In factory defaults, there was no option to switch on the ePOS Service.
