 The library allows to print receipts using an ESC/POS thermal WiFi/Ethernet printer. For Bluetooth printers, use [esc_pos_bluetooth](https://github.com/andrey-ushakov/esc_pos_bluetooth) library.

 It can be used in [Flutter](https://flutter.dev/) or pure [Dart](https://dart.dev/) projects. For Flutter projects, both Android and iOS are supported.
 
 To scan for printers in your network, consider using [ping_discover_network](https://pub.dev/packages/ping_discover_network) package. Note that most of the ESC/POS printers by default listen on port 9100.

 ## Tested Printers
 Here are some [printers tested with this library](printers.md). Please add your models you have tested to maintain and improve this library and help others to choose the right printer.
 
-## Main Features
-* Connect to Wi-Fi / Ethernet printers
-* Simple text printing using *text* method
-* Tables printing using *row* method
-* Text styling:
-  * size, align, bold, reverse, underline, different fonts, turn 90°
-* Print images
-* Print barcodes
-  * UPC-A, UPC-E, JAN13 (EAN13), JAN8 (EAN8), CODE39, ITF (Interleaved 2 of 5), CODABAR (NW-7)
-* Paper cut (partial, full)
-* Beeping (with different duration)
-* Paper feed, reverse feed
 
-**Note**: Your printer may not support some of the presented features (especially for underline styles, partial/full paper cutting, reverse feed, ...).

-      width: 3,

-### Print an image:
-
-This package implements 3 ESC/POS functions:
-* `ESC *` - print in column format
-* `GS v 0` - print in bit raster format (obsolete)
-* `GS ( L` - print in bit raster format
-
-Note that your printer may support only some of the above functions.
+You can find more examples here: [esc_pos_utils](https://github.com/andrey-ushakov/esc_pos_utils).

-import 'dart:io';

-final ByteData data = await rootBundle.load('assets/logo.png');

-// Using `ESC *`
-ticket.image(image);

-### Print a barcode:

-### Print a QR Code:

-To print a QR Code, add [qr_flutter](https://pub.dev/packages/qr_flutter) and [path_provider](https://pub.dev/packages/path_provider) as a dependency in your `pubspec.yaml` file.
-```dart
-String qrData = "google.com";

-## Using Code Tables
-Thanks to the [charset_converter](https://pub.dev/packages/charset_converter) package, it's possible to print in different languages. The source text should be encoded using the corresponding charset and the correct charset should be passed to the `Ticket.textEncoded` method.
-
-Here are some examples:
-```dart
-/// Portuguese
-Uint8List encTxt1 = await CharsetConverter.encode(
-    "cp860", "Portuguese: Olá, Não falo português, Cão");
-ticket.textEncoded(encTxt1,
-    styles: PosStyles(codeTable: PosCodeTable.pc860_1));
-
-/// Greek
-Uint8List encTxt2 =
-    await CharsetConverter.encode("windows-1253", "Greek: αβγδώ");
-ticket.textEncoded(encTxt2,
-    styles: PosStyles(codeTable: PosCodeTable.greek));
-
-/// Polish
-Uint8List encTxt3 = await CharsetConverter.encode(
-    "cp852", "Polish: Dzień dobry! Dobry wieczór! Cześć!");
-ticket.textEncoded(encTxt3,
-    styles: PosStyles(codeTable: PosCodeTable.pc852_1));
-
-/// Russian
-Uint8List encTxt4 =
-    await CharsetConverter.encode("cp866", "Russian: Привет мир!");
-ticket.textEncoded(encTxt4,
-    styles: PosStyles(codeTable: PosCodeTable.pc866_2));
-
-/// Thai: x-mac-thai | iso-8859-11 | cp874
-Uint8List encThai =
-    await CharsetConverter.encode("cp874", "Thai: ใบเสร็จ-ใบรับผ้า");
-ticket.textEncoded(encThai,
-    styles: PosStyles(codeTable: PosCodeTable.thai_1));
-
-/// Arabic
-/// Possible charsets for CharsetConverter.encode: cp864, windows-1256
-/// Possible codeTables for PosStyles: arabic, pc864_1, pc864_2, pc1001_1, pc1001_2, wp1256, pc720
-Uint8List encArabic = await CharsetConverter.encode("windows-1256", "اهلا");
-ticket.textEncoded(encArabic,
-    styles: PosStyles(codeTable: PosCodeTable.arabic));
-```
+For a complete example, check `example/example.dart` and `example/discover_printers`.
 
-Note that `CharsetConverter.encode` takes a platform-specific charset (check the [library documentation](https://pub.dev/packages/charset_converter) for more info).
 
-Note that different printers may support different sets of codetables and the above examples may not work on some printer models. It's also possible to pass a codetable by its code (according to your printer's documentation): `PosStyles(codeTable: PosCodeTable(7))`.
+## How to Help
+* Test your printer and add it in the table: [Wifi/Network printer](https://github.com/andrey-ushakov/esc_pos_printer/blob/master/printers.md) or [Bluetooth printer](https://github.com/andrey-ushakov/esc_pos_bluetooth/blob/master/printers.md)
+* Test and report bugs
+* Share your ideas about what could be improved (code optimization, new features...)
