-# Quick Printer
-## Android POS Printer (ESC/POS)
-> Created for the purpose of serving as a channel among other applications that require printing data on receipt printers using ESC/POS commands.
-
-## __Introduction__
-Quick printer is an Android application that allows you to add and configure receipt printers (POS printers) through different connection types:
-- Wifi local network
-- Bluetooth
-- USB (OTG)
-
-The most important thing is that it allows you to print the text you share from any application, so you can print your favorite texts.
-
-And if you're a developer, you can integrate your application in a super simple way so you can print tickets, receipts, etc.
-
-> The application supports many types of thermal and matrix printers such as EPSON, BIXOLON, STAR MICRONICS, CITIZEN, etc.
-
-
-## __Usage__
-The steps for using the application will be detailed below:
-
-### __1. Download Quick Printer from the playstore [here](https://play.google.com/store/apps/details?id=pe.diegoveloper.printerserverapp "Quick Printer")__
-    
-  <center><img src="http://www.qr-code-generator.com/phpqrcode/getCode.php?cht=qr&chl=https%3A%2F%2Fplay.google.com%2Fstore%2Fapps%2Fdetails%3Fid%3Dpe.diegoveloper.printerserverapp&chs=180x180&choe=UTF-8&chld=L|0" width="200"></center>     
-    Configure your printers using the Tutorial inside de app.
-  
-### __2. Share Text from any application installed__  
-    When the application selection dialog appears, select 'Quick Printer'.  
-    The selected text will be printed on your previously configured printer.
-    
-    
-## __NON Developers__
-If you are a user without knowledge of programming, you can use the app just sharing text, try sharing text from any app, like SMS, Whatsapp, Browser(copy the Text you need, NOT the URL), etc.
-
-- Select the Text

- 
-- Press SHARE
-- Select Quick Printer
-
-You can use any command from these list: https://github.com/diegoveloper/quickprinter#commands-supported
-
-
-## __Developers__
-If you are a developer and want to integrate your Android application with 'Quick Printer', read the following instructions:
-
-* ### Using Sharing Intents
-You can share plain text using shared Intents with the appropriate commands, below the simplest example.  
- ```java 
-        String textToPrint = "Your text here"; 
-        Intent intent = new Intent("pe.diegoveloper.printing"); 
-         //intent.setAction(android.content.Intent.ACTION_SEND);  
-        intent.setType("text/plain"); 
-        intent.putExtra(android.content.Intent.EXTRA_TEXT,textToPrint); 
-        startActivity(intent); 
- ```
- When the selection dialog appears, select 'Quick Printer'.
-
-* ### Using Sharing Intents with commands
-You can specify different printer commands in your sharing text to take advantage of your printer. This is an example of how to use the commands. 
- ```java  
-
-        String textToPrint = "<BIG>Text Title<BR>Testing <BIG>BIG<BR><BIG><BOLD>" +
-                "string <SMALL> text<BR><LEFT>Left aligned<BR><CENTER>" +
-                "Center aligned<BR><UNDERLINE>underline text<BR><QR>12345678<BR>" +
-                "<CENTER>QR: 12345678<BR>Line<BR><LINE><BR>Double Line<BR><DLINE><BR><CUT>";  
-        Intent intent = new Intent("pe.diegoveloper.printing"); 
-        //intent.setAction(android.content.Intent.ACTION_SEND);  
-        intent.setType("text/plain");  
-        intent.putExtra(android.content.Intent.EXTRA_TEXT,textToPrint);  
-        startActivity(intent);  
- ```  
- These commands generate this ticket

- 
-* ### Getting the print result
-If you want to get the printing result you should use  startActivityForResult instead of startActivity, below is the sample code
-
-## Old versions of Android
-
-Call the printer
-
-```java  
-        Intent intent = new Intent("pe.diegoveloper.printing"); 
-        //intent.setAction(android.content.Intent.ACTION_SEND);
-        intent.setType("text/plain");
-        intent.putExtra(android.content.Intent.EXTRA_TEXT,"your text to print here");
-        startActivityForResult(intent,YOUR_REQUEST_CODE);  
-``` 
- 
-Receive the data
-
-```java
-        @Override
-       protected void onActivityResult(int requestCode, int resultCode, Intent data) {
-       // super.onActivityResult(requestCode, resultCode, data);
-        if (requestCode == YOUR_REQUEST_CODE){
-            if (resultCode == RESULT_OK){
-                //Printing is ok
-            } else {
-                if (data != null) {
-                    String errorMessage = data.getStringExtra("errorMessage");  
-                    //Printing with error
-                }
-            }
-          }
-        }
-```
-
-## New versions of Android
-
-Call the printer
-        
-```java       
-        Intent intent = new Intent("pe.diegoveloper.printing"); 
-        intent.setType("text/plain");
-        intent.putExtra(android.content.Intent.EXTRA_TEXT,"your text to print here");
-        myActivityResultLauncher.launch(intent);
-       
- ``` 
- 
- Receive the data
- 
- ```java
-               
-            ActivityResultLauncher<Intent> myActivityResultLauncher = registerForActivityResult(
-            new ActivityResultContracts.StartActivityForResult(),
-            result -> {
-                if (result.getResultCode() == Activity.RESULT_OK) {
-                    //Printing is ok
-
-                } else {
-                    Intent data = result.getData();
-                    if (data != null) {
-                        String errorMessage = data.getStringExtra("errorMessage");
-                        //Printing with error
-                    }
-                }
-            });
- ```           
-  
-* ### Printing on a specific printer by alias
-If you want to send the data to a specific printer (replacing printer selection), You can do following the snippet code 
- ```java  
-        String data = "<PRINTER alias='your_printer_alias'> YOUR CUSTOM DATA <BR><CUT>"; 
-        Intent intent = new Intent("pe.diegoveloper.printing"); 
-       // intent.setAction(android.content.Intent.ACTION_SEND);
-        intent.setType("text/plain");
-        intent.putExtra(android.content.Intent.EXTRA_TEXT,data);
-        startActivityForResult(intent,YOUR_REQUEST_CODE);  
-  ``` 
-  
-If you want to print the same commands on multiple printers, you can use multiple alias separated by `,`.
- ```java  
-        String data = "<PRINTER alias='alias1, alias2, alias3'> YOUR CUSTOM DATA <BR><CUT>";   
- ``` 
-    
-* ### Printing on a specific printer by group
-We introduced groups, now you can add groups and assign it to any printer, so multiple printers can be part of a group (replacing printer selection), You can do following the snippet code 
- ```java  
-        String data = "<PRINTER group='your_printer_group'>YOUR CUSTOM DATA <BR><CUT>"; 
-        Intent intent = new Intent("pe.diegoveloper.printing"); 
-       // intent.setAction(android.content.Intent.ACTION_SEND);
-        intent.setType("text/plain");
-        intent.putExtra(android.content.Intent.EXTRA_TEXT,data);
-        startActivityForResult(intent,YOUR_REQUEST_CODE);  
-```
-  
-* ### Printing your receipt 'n' times
-    
-If you want to print your receipt 'n' times, You can do following the snippet code 
- ```java  
-        String data = "<PRINTER repeat='4'> YOUR CUSTOM DATA <BR><CUT>"; 
-        Intent intent = new Intent("pe.diegoveloper.printing");
-        intent.setType("text/plain");
-        intent.putExtra(android.content.Intent.EXTRA_TEXT,data);
-        startActivityForResult(intent,YOUR_REQUEST_CODE);  
-  ```

-Learn how to receive the data: https://github.com/diegoveloper/quickprinter#getting-the-print-result 
-
-    
-    
-  
-* ### Print from web
-You can print directly from your website using schemas, for example if you want to print the following commands: 
- ```java  
-         String commands = "test printer<br><big>Big title<br><cut>";
-  ``` 
-  You have to write this on your web page: 
- ```html
-    <script>
-function sendToQuickPrinter(){
-     var text = "test printer<br><big>Big title<br><cut>";
-     var textEncoded = encodeURI(text);
-     window.location.href="quickprinter://"+textEncoded;
-}
-
-//if you are using latest version of chrome browser I recommend to use:
-function sendToQuickPrinterChrome(){
-     var text = "test printer<br><big>Big title<br><cut>";
-     var textEncoded = encodeURI(text);
-     window.location.href="intent://"+textEncoded+"#Intent;scheme=quickprinter;package=pe.diegoveloper.printerserverapp;end;";
-     
-}
-</script>
-
-<a onclick="sendToQuickPrinter();">Print Button</a>
-  ``` 
-  All you need to do is specify the quickprinter schema:// followed by the encoded data (you could use encodeURI method from javascript) you want to print.
-  If you are using Apache Cordova and want to print from web, You must add this line on your config.xml file :  
- ```html
-  <allow-intent href="quickprinter://*" />
- ```
-  Testing printer from your chrome browser (Open this link from your android phone) https://quickprinter-d2410.firebaseapp.com/
