+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
+ 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
+ text("Hello World!\n");
+$printer -> cut();
+$printer -> close();
+```
+
+Or to a local printer:
+```php
+ 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.
+
+Compatibility
+-------------
+
+### Interfaces and operating systems
+This driver is known to work with the following OS/interface combinations:
+
+
+
+### Printers
+Many thermal receipt printers support ESC/POS to some degree. This driver has been known to work with:
+
+- EPOS TEP 220M
+- Epson TM-T88III
+- Epson TM-T88IV
+- Epson TM-T70
+- Epson TM-T82II
+- Epson TM-T20
+- Epson TM-T70II
+- Epson TM-U220
+- Epson FX-890 (requires `feedForm()` to release paper).
+- Okipos 80 Plus III
+- P-822D
+- SEYPOS PRP-300 (Also marketed as TYSSO PRP-300)
+- Star TSP-650
+- Star TUP-592
+- Xprinter XP-Q800
+- Zijang NT-58H
+- Zijang ZJ-5870
+- Zijang ZJ-5890T (Marketed as POS 5890T)
+
+If you use any other printer with this code, please let me know so I can add it to the list.
+
+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 $size`: Output size modifier for the image.
+
+Size modifiers are:
+
+- `IMG_DEFAULT` (leave image at original size)
+- `IMG_DOUBLE_WIDTH`
+- `IMG_DOUBLE_HEIGHT`
+
+A minimal example:
+
+```php
+ graphics($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`
+
+### setBarcodeHeight($height)
+Set barcode height.
+
+Parameters:
+
+- `int $height`: Height in dots. If not specified, 8 will be used.
+
+### setDoubleStrike($on)
+Turn double-strike mode on/off.
+
+Parameters:
+
+- `boolean $on`: true for double strike, false for no double strike.
+
+### setEmphasis($on)
+Turn emphasized mode on/off.
+
+Parameters:
+
+- `boolean $on`: true for emphasis, false for no emphasis.
+
+### setFont($font)
+Select font. Most printers have two fonts (Fonts A and B), and some have a third (Font C).
+
+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).
+- `int $heightMultiplier`: Multiple of the regular height to use (range 1 - 8).
+
+### setUnderline($underline)
+Set underline for printed text.
+
+Parameters:
+
+- `int $underline`: Either `true`/`false`, or one of `Escpos::UNDERLINE_NONE`, `Escpos::UNDERLINE_SINGLE` or `Escpos::UNDERLINE_DOUBLE`. Defaults to `Escpos::UNDERLINE_SINGLE`.
+
+### text($str)
+Add text to the buffer. Text should either be followed by a line-break, or `feed()` should be called after this.
+
+Parameters:
+
+- `string $str`: The string to print.
+
+Further notes
+-------------
+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.

+# All text after a double hash (##) is considered a comment and is placed in
+# front of the TAG it is preceding.
+#
+# All text after a single hash (#) is considered a comment and will be ignored.
+# The format is:
+# TAG = value [value, ...]
+# For lists, items can also be appended using:
+# TAG += value [value, ...]
+# Values that contain spaces should be placed between quotes (\" \").
+
+#---------------------------------------------------------------------------
+# Project related configuration options
+#---------------------------------------------------------------------------
+
+# This tag specifies the encoding used for all characters in the config file
+# that follow. The default is UTF-8 which is also the encoding used for all text
+# before the first occurrence of this tag. Doxygen uses libiconv (or the iconv
+# built into libc) for the transcoding. See http://www.gnu.org/software/libiconv
+# for the list of possible encodings.
+# The default value is: UTF-8.
