+ESC/POS Print Driver for PHP
+============================
+This project implements a subset of Epson's ESC/POS protocol for thermal receipt printers. It allows you to generate and print receipts with basic formatting, cutting, and barcodes on a compatible printer.
+
+The library was developed to add drop-in support for receipt printing to any PHP app, including web-based point-of-sale (POS) applications.
+
+Basic usage
+-----------
+A "hello world" receipt can be generated easily (Call this `hello-world.php`):
+```php
+<?php
+require_once(dirname(__FILE__) . "/Escpos.php");
+$printer = new Escpos();
+$printer -> text("Hello World!\n");
+$printer -> cut();
+$printer -> close();
+```
+This would be printed as:
+```
+# Networked printer
+php hello-world.php | nc 10.x.x.x. 9100
+# Local printer
+php hello-world.php > /dev/...
+# Windows local printer
+php hello-world.php > foo.txt
+net use LPT1 \\server\printer
+copy foo.txt LPT1
+del foo.txt
+```
+
+From your web app, you could pass the output directly to a socket if your printer is networked:
+```php
+<?php
+require_once(dirname(__FILE__) . "/Escpos.php");
+$connector = new NetworkPrintConnector("10.x.x.x", 9100);
+$printer = new Escpos($connector);
+$printer -> text("Hello World!\n");
+$printer -> cut();
+$printer -> close();
+```
+
+Or to a local printer:
+```php
+<?php
+require_once(dirname(__FILE__) . "/Escpos.php");
+$connector = new FilePrintConnector("/dev/ttyS0");
+$printer = new Escpos($connector);
+$printer -> text("Hello World!\n");
+$printer -> cut();
+$printer -> close();
+```
+
+### Basic workflow
+The library should be initialised with a PrintConnector, which will pass on the data to your printer.
+Use the table under "Compatibility", or the examples below to choose the appropriate connector for your
+platform & interface. If no connector is specified, then standard output is used.
+
+When you have finished using the print object, call `close()` to finalize any data transfers.
+
+### Tips & examples
+On Linux, your printer device file will be somewhere like `/dev/lp0` (parallel), `/dev/usb/lp1` (USB), `/dev/ttyUSB0` (USB-Serial), `/dev/ttyS0` (serial).
+
+On Windows, the device files will be along the lines of `LPT1` (parallel) or `COM1` (serial). Use the `WindowsPrintConnector` to tap into system printing on Windows (eg. [Windows USB](https://github.com/mike42/escpos-php/tree/master/example/interface/windows-usb.php), [SMB](https://github.com/mike42/escpos-php/tree/master/example/interface/smb.php) or [Windows LPT](https://github.com/mike42/escpos-php/tree/master/example/interface/windows-lpt.php)) - this submits print jobs via a queue rather than communicating directly with the printer.
+
+A complete real-world receipt can be found in the code of [Auth](https://github.com/mike42/Auth) in [ReceiptPrinter.php](https://github.com/mike42/Auth/blob/master/lib/misc/ReceiptPrinter.php). It includes justification, boldness, and a barcode.
+
+Other examples are located in the [example/](https://github.com/mike42/escpos-php/blob/master/example/) directory.
+

+
+Available methods
+-----------------
+
+### __construct(PrintConnector $connector, AbstractCapabilityProfile $profile)
+Construct new print object.
+
+Parameters:
+- `PrintConnector $connector`: The PrintConnector to send data to. If not set, output is sent to standard output.
+- `AbstractCapabilityProfile $profile` Supported features of this printer. If not set, the DefaultCapabilityProfile will be used, which is suitable for Epson printers.
+
+See [example/interface/]("https://github.com/mike42/escpos-php/tree/master/example/interface/) for ways to open connections for different platforms and interfaces.
+
+### barcode($content, $type)
+Print a barcode.
+
+Parameters:
+
+- `string $content`: The information to encode.
+- `int $type`: The barcode standard to output. If not specified, `Escpos::BARCODE_CODE39` will be used.
+
+Currently supported barcode standards are (depending on your printer):
+
+- `BARCODE_UPCA`
+- `BARCODE_UPCE`
+- `BARCODE_JAN13`
+- `BARCODE_JAN8`
+- `BARCODE_CODE39`
+- `BARCODE_ITF`
+- `BARCODE_CODABAR`
+
+Note that some barcode standards can only encode numbers, so attempting to print non-numeric codes with them may result in strange behaviour.
+
+### bitImage(EscposImage $image, $size)
+See [graphics()](#graphicsescposimage-image-size) below.
+
+### cut($mode, $lines)
+Cut the paper.
+
+Parameters:
+
+- `int $mode`: Cut mode, either `Escpos::CUT_FULL` or `Escpos::CUT_PARTIAL`. If not specified, `Escpos::CUT_FULL` will be used.
+- `int $lines`: Number of lines to feed before cutting. If not specified, 3 will be used.
+
+### feed($lines)
+Print and feed line / Print and feed n lines.
+
+Parameters:
+
+- `int $lines`: Number of lines to feed
+
+### feedForm()
+Some printers require a form feed to release the paper. On most printers, this command is only useful in page mode, which is not implemented in this driver.
+
+### feedReverse($lines)
+Print and reverse feed n lines.
+
+Parameters:
+
+- `int $lines`: number of lines to feed. If not specified, 1 line will be fed.
+
+### graphics(EscposImage $image, $size)
+Print an image to the printer.
+
+Parameters:
+
+- `EscposImage $img`: The image to print.
+- `int $size`: Output size modifier for the image.
+
+Size modifiers are:
+
+- `IMG_DEFAULT` (leave image at original size)
+- `IMG_DOUBLE_WIDTH`
+- `IMG_DOUBLE_HEIGHT`
+
+A minimal example:
+
+```php
+<?php
+$img = new EscposImage("logo.png");
+$printer -> graphics($img);
+```
+
+See the [example/](https://github.com/mike42/escpos-php/blob/master/example/) folder for detailed examples.
+
+The function [bitImage()](#bitimageescposimage-image-size) takes the same parameters, and can be used if your printer doesn't support the newer graphics commands.
+
+### initialize()
+Initialize printer. This resets formatting back to the defaults.
+
+### pulse($pin, $on_ms, $off_ms)
+Generate a pulse, for opening a cash drawer if one is connected. The default settings (0, 120, 240) should open an Epson drawer.
+
+Parameters:
+
+- `int $pin`: 0 or 1, for pin 2 or pin 5 kick-out connector respectively.
+- `int $on_ms`: pulse ON time, in milliseconds.
+- `int $off_ms`: pulse OFF time, in milliseconds.
+
+### qrCode($content, $ec, $size, $model)
+Print the given data as a QR code on the printer.
+
+- `string $content`: The content of the code. Numeric data will be more efficiently compacted.
+- `int $ec` Error-correction level to use. One of `Escpos::QR_ECLEVEL_L` (default), `Escpos::QR_ECLEVEL_M`, `Escpos::QR_ECLEVEL_Q` or `Escpos::QR_ECLEVEL_H`. Higher error correction results in a less compact code.
+- `int $size`: Pixel size to use. Must be 1-16 (default 3)
+- `int $model`: QR code model to use. Must be one of `Escpos::QR_MODEL_1`, `Escpos::QR_MODEL_2` (default) or `Escpos::QR_MICRO` (not supported by all printers).
+
+### selectPrintMode($mode)
+Select print mode(s).
+
+Parameters:
+
+- `int $mode`: The mode to use. Default is `Escpos::MODE_FONT_A`, with no special formatting. This has a similar effect to running `initialize()`.
+
+Several MODE_* constants can be OR'd together passed to this function's `$mode` argument. The valid modes are:
+
+- `MODE_FONT_A`
+- `MODE_FONT_B`
+- `MODE_EMPHASIZED`
+- `MODE_DOUBLE_HEIGHT`
+- `MODE_DOUBLE_WIDTH`
+- `MODE_UNDERLINE`

+
+Parameters:
+
+- `int $font`: The font to use. Must be either `Escpos::FONT_A`, `Escpos::FONT_B`, or `Escpos::FONT_C`.
+
+### setJustification($justification)
+Select justification.

+Parameters:
+
+- `int $justification`: One of `Escpos::JUSTIFY_LEFT`, `Escpos::JUSTIFY_CENTER`, or `Escpos::JUSTIFY_RIGHT`.
+
+### setReverseColors($on)
+Set black/white reverse mode on or off. In this mode, text is printed white on a black background.
+
+Parameters:
+
+- `boolean $on`: True to enable, false to disable.
+
+### setTextSize($widthMultiplier, $heightMultiplier)
+Set the size of text, as a multiple of the normal size.
+
+Parameters:
+
+- `int $widthMultiplier`: Multiple of the regular height to use (range 1 - 8).

+Posts I've written up for people who are learning how to use receipt printers:
+
+* [What is ESC/POS, and how do I use it?](http://mike.bitrevision.com/blog/what-is-escpos-and-how-do-i-use-it), which documents the output of test.php.
+* [Setting up an Epson receipt printer](http://mike.bitrevision.com/blog/2014-20-26-setting-up-an-epson-receipt-printer)
+* [Getting a USB receipt printer working on Linux](http://mike.bitrevision.com/blog/2015-03-getting-a-usb-receipt-printer-working-on-linux)
+
+Other versions
+--------------
+Some forks of this project have been developed by others for specific use cases. Improvements from the following projects have been incorporated into escpos-php:
+
+- [wdoyle/EpsonESCPOS-PHP](https://github.com/wdoyle/EpsonESCPOS-PHP)
+- [ronisaha/php-esc-pos](https://github.com/ronisaha/php-esc-pos)
+
+Vendor documentation
+--------------------
+Epson notes that not all of its printers support all ESC/POS features, and includes a table in their documentation:
+
+* [FAQ about ESC/POS from Epson](http://content.epson.de/fileadmin/content/files/RSD/downloads/escpos.pdf)
+
+Note that many printers produced by other vendors use the same standard, and are compatible by varying degrees.

+Examples
+--------
+
+This folder contains a collectoion of feature examples.
+Generally, demo.php is the fastest way to find out which features your
+printer supports.
+
+## Subfolders
+- `interface/` - contains examples for output interfaces: eg, parallel, serial, USB, network, file-based.
+- `specific/` - examples made in response to issues & questions. These cover specific languages, printers and interfaces, so hit narrower use cases.
+
+## List of examples
+
+Each example prints to standard output, so either edit the print connector, or redirect the output to your printer to see it in action. They are designed for developers: open them in a text editor before you run them!
+
+- `bit-image.php` - Prints a images to the printer using the older "bit image" commands.
+- `demo.php` - Demonstrates output using a large subset of availale features.
+- `qr-code.php` - Prints QR codes, if your printer supports it.
+- `character-encodings.php` - Shows available character encodings. Change from the DefaultCapabilityProfile to get more useful output for your specific printer.
+- `graphics.php` - The same output as `bit-image.php`, printed with the newer graphics commands (not supported on many non-Epson printers)
+- `receipt-with-logo.php` - A simple receipt containing a logo and basic formating.
+- `character-encodings-with-images.php` - The same as `character-encodings.php`, but also prints each string using an `ImagePrintBuffer`, showing compatibility gaps.
+- `print-from-html.php` - Runs `wkhtmltoimage` to convert HTML to an image, and then prints the image. (This is very slow)
+- `character-tables.php` - Prints a compact character code table for each available character set. Used to debug incorrect output from `character-encodings.php`.
+- `print-from-pdf.php` - Loads a PDF and prints each page in a few different ways (very slow as well)

+Interfaces
+----------
+This directory contains boilerpalte code to show you how to open a print connector
+to printers which are connected in different ways.
+
+To get a list of supported interfaces and operating systems, see the main README.md file for the project.
+
+If you have a printer interface with no example, and you want to help put one together, then please lodge a request on the bug tracker: https://github.com/mike42/escpos-php/issues
