Hi,

When I try to change charsetName from windows-1252 in ThermalPrinterCordovvaPlugin.java
charsetEncoding = new EscPosCharsetEncoding( charsetEncodingData.optString("charsetName","CP737"),charsetEncodingData.optInt("charsetId", 16));
(same applies for every other charsetName, always returns windows-1252)
The printer settings are setup to CP737 and are working properly when printing test-page.
Running getEncoding still returns windows-1252

Any ideas whay might causing this?

Hello, i using this plugin in my project use framework7-vue. Now i have an error= "listPrinters is not defined"
this is test code:
methods: {
login: function () {
listPrinters(
"bluetooth",
function (s) {
console.log("OK",s);
},
function (r) {
console.log("Err" + r);
}
);
},
}

I use the plugin to my Ionic / Angular App, the plugin seems to work, i can list the available devices.. etc. However, when i use the function ThermalPrinter.printFormattedText it console logs me that the print was successfull but my printer doesnt print. I use the LK-P30II bluetooth thermal printer.
Sample of my code
`print() {
let self = this;
window.ThermalPrinter.printFormattedText({
type: 'bluetooth',
id: 'my name', // You can also use the identifier directly i. e. 00:11:22:33:44:55 (address) or name
text: '[C]Hello World' // new lines with "\n"
}, function() {
console.log('Successfully printed!');
}, function(error: any) {
console.error('Printing error', error);
});

}`

Hello, thanks for the library but i haven't been able to make it work, i am printing with TCP.
I pass all necessary fields, but it keeps crashing but if i take out the ID property from the data object, i doesn't crash but i get an error telling me to pass the ID but when i do the app crashes.

[App crash only happens when i call the function]

function requestPermission() { var IPAddress = "192.168.1.240"; var port = 9100; console.log(IPAddress, port); if (ThermalPrinter.printFormattedText) { ThermalPrinter.printFormattedTextAndCut( { type: "tcp", id: "192.168.1.240:9100", // i have also tried "192.168.1.2409100 address: IPAddress, port: port, }, function (success) { console.log(success, "SUCCESS"); }, function (error) { console.log(error, "ERROR"); } ); } }

Thanks.

Hi! 👋

Firstly, thanks for your work on this project! 🙂

Today I used patch-package to patch [email protected] for the project I'm working on.

Here is the diff that solved my problem:

Can we print base64 pdf using this?

I am facing an issue with my code where I am attempting to print an image on a thermal printer using the bitmapToHexadecimalString() function. However, the image is not being printed on the paper. I would appreciate any assistance in identifying and resolving the problem.

Here is the code I am using:

    ThermalPrinter.bitmapToHexadecimalString({
         type: 'bluetooth',
         id: '00:11:22:33:44:55',
         base64: base64txt
     }, function() {
         alert('Successfully printed!');
     }, function(error) {
         alert('Printing error: ' + error);
    });

I'm trying to print receipts using the align properties, but when the product name is too long the formatting is broken, is there any way to implement a table?

DantSu/ESCPOS-ThermalPrinter-Android

Alignment is not working properly in 3inch paper.

new EscPosPrinter(printerConnection, 203, 76f, 48)

This seems to solve the issue, but in this repo i dont see any option for setting this.

Also setting encoding is not avaiable but getiing encoding is available !

Just tried on capacitor 5 but it does not work. SDK30&31 both does not work.
The error i see is the following:

tPrinter is declared and used as per sample on the main page:

`
import { Printer, ThermalPrinterPlugin } from 'thermal-printer-cordova-plugin/src';

declare let tPrinter: ThermalPrinterPlugin;

tPrinter.listPrinters({type: 'bluetooth'}, function(printers) {
        alert(printers);
        if (printers.length > 0) {
            var pr = printers[0] as Printer;
            tPrinter.requestPermissions({
                type: 'bluetooth',
                id: 'SPP-R400'
            }, function() {
                // Permission granted - We can print!
                tPrinter.printFormattedText({
                    type: 'bluetooth',
                    id: 4,
                    text: '[C]<u> Hello World</u>' // new lines with "\n"
                }, function() {
                    console.log('Successfully printed!');
                }, function(error) {
                    console.error('Printing error', error);
                });
            }, function(error) {
                alert('Permission');
                console.error('Permission denied - We can\'t print!');
            });
        } else {
            console.error('No printers found!');
        }
    }, function(error) {
        console.error('Ups, we cant list the printers!', error);
    });

Another problem is that when you install it from npm:
npm install thermal-printer-cordova-plugin it will install a version old 2 years so the package also on npmjs should be updated.

How To Trigger Kick Out Cash Drawer using Thermal printer connect with RJ11 cable to cashdrawer when After Printed??

Hi,

when I try to set printerWidthMM in PrintFormattedText I get the following error: 'printerWidthMM' does not exist in type 'PrintFormattedText'

I looked at the underlying library and it looks like it only accepts text and dotsFeedPaper.

i convert image to base64 then use it in bitmap function like :
ThermalPrinter.bitmapToHexadecimalString({
type: 'tcp',
address: '192.168.1.100',
port: 9100,
id: '192.168.1.100:9100', // Use an unique identifier for each printer i. e. address:port or name
base64:imageData
}, function () {
console.log('Successfully printed!');
}, function (error) {
console.error('Printing error', error);
});

Thank you for this amazing library. I have decided to use the TCP, as USB was working well. Now the whole App crash and I cannot see what is wrong. I have spent so long time trying to read the logcat logs, but did not manage to find anaything.

I am using ionic framework with this library. Any help would be appreciated!

let port = 68;
let ip = '192.168.0.187';
let deviceId = ${ip}:${port};
await this.thermal.printFormattedTextAndCut({
type: "tcp",
address: ip,
port: port,
id: deviceId,
text: 'testing please',
mmFeedPaper: 20,
printerWidthMM: 80,
}).then(res => {
console.log(res);

}).catch(err => {
console.log(err);
});

is there any proble in my code ? thank you

how we can connect printer before print for avoiding connection reset and broken pipe issue like if there is any way to calling this private EscPosPrinter getPrinter(CallbackContext callbackContext, JSONObject data) i think problem will be solved

Hi @patrickbussmann

This is a great plugin.

Can we Charset Encoding ?
Hope can print word in Traditional Chinese.

Thank you very much

why on certain device happen this error? i already add this permission though <uses-permission android:name="android.permission.DISABLE_KEYGUARD" /> but still appear same error message. Is anyone ever happen same error?

Hey

How can i open the Cash-Drawer?

when i was trying to print after few prints showing error Connection reset and Broken pipe issue can you please guide me how we can solve this issue

Hi We have updates the ionic capacitor 4 app to maxSdkVersion 32. Now we are facing this error Missing permission for android.permission.DISABLE_KEYGUARD

As per the official document we need to change to this "If you want your device to be communicable with other devices, you must add BLUETOOTH_CONNECT permission."

So we have made the below changes in AndroidManifest.xml file but no use.

<uses-permission android:name="android.permission.BLUETOOTH_CONNECT" />
<uses-permission android:maxSdkVersion="30" android:name="android.permission.BLUETOOTH" />

Hi all,

I have two different android devices with two different bluetooth printers.

I have different behaviours related with text text lone height.

See attached image please.

Is there any way to control this?

Thanks a lot.

I can't access printerWidth ?!

what can i do to change font size, i try with size='big-3' not working, only working if use size='big'. I try to update com.github.DantSu:ESCPOS-ThermalPrinter-Android:2.0.8 to com.github.DantSu:ESCPOS-ThermalPrinter-Android:3.2.1 but error in build gradle...

Hi, i need some help here, i tried to build the app with the plugin, and the build failed with many lines of error saying there are duplicate classes. I am building this on android 10.0.1 targetSDKversion 30. Would this be anything to do with the androidX update? Because i tried to update the app onto playstore and the min target version is 30, which requires the android 10.0.1

Below is part of the build error.

• What went wrong:
  Execution failed for task ':app:checkDebugDuplicateClasses'.

A failure occurred while executing com.android.build.gradle.internal.tasks.CheckDuplicatesRunnable
Duplicate class com.google.zxing.BarcodeFormat found in modules jetified-barcodescanner-release-2.1.5-runtime (:barcodescanner-release-2.1.5:) and jetified-core-3.4.0 (com.google.zxing:core:3.4.0)

Thanks!

hi patrickbussmann
i am using your paystory-de/thermal-printer-cordova-plugin
URL https://github.com/paystory-de/thermal-printer-cordova-plugin
i use all the function on document and all are work find
can you provide any document or any other link to
get getNbrCharactersPerLine() ,getPrinterWidthMM() , getPrinterDpi() and other method
how i get these thing in my application

and how i use ESC/POS commands (https://www.sparkag.com.br/wp-content/uploads/2016/06/ESC_POS-AK912-English-Command-Specifications-V1.4.pdf)

Hello Awesome Community!

I just wanted to know if there were any one else who is experiencing this issue?

When I use "[C]<img>IMAGE DATA</img> the image is printed allright, but is not centered properly.

It looks like the plugin takes the pivot from far left side and centers it instead of taking the pivot from the center of the image.
The image I am using is 350px, Square.

Anyone else experiencing this issue?

I am using a Sunmi V2 Pro device which has an integrated printer.

I am using your ESC POS library to print receipts and having the following issue.
Only on these sunmi devices, there is a preceding 'r' printed before the 1st character.

I'm using this plugin with capacitor, vuejs and vuetify and I can't call any method because it keeps saying 'ThermalPrinter' is undefined. Is there another way I could use it?

Hello, I would like to congratulate you on the development of this excellent plugin. But I had a problem when I used the barcode-scanner plugin.

Do you suggest any kind of modification I can make?

I have a bunch of duplicate class errors, how do I solve this? I tried a lot of solutions online and I couldn't
like this in my build.gradle:

dependencies {
    configurations.all {
        exclude group: 'com.google.zxing'
    }
}

and I couldn't solve it, how do I fix when two cordova plugins is exporting same class ?

Do you have a quick example file about how to test this plugin?
I used the TCP Code Example on this page https://github.com/DantSu/ESCPOS-ThermalPrinter-Android
but it seems that it is not doing anything, no errors or warnings.
Thank you

When I try to import it to my Vue js application I get this error. Is there an extra step that I am missing?

I am importing it like this
import { ThermalPrinterPlugin } from 'thermal-printer-cordova-plugin/src';

The error I get

`This dependency was not found:

• thermal-printer-cordova-plugin/src in ./node_modules/cache-loader/dist/cjs.js??ref--13-0!./node_modules/babel-loader/lib!./node_modules/cache-loader/dist/cjs.js??ref--1-0!./node_modules/vue-loader-v16/dist??ref--1-1!./src/views/Dashboard.vue?vue&type=script&lang=js

To install it, you can run: npm install --save thermal-printer-cordova-plugin/src`
