## Basic usage



### Include the library



#### Composer



This library is designed for use with the `composer` PHP dependency manager. Simply add the `mike42/escpos-php` package to get started:



```bash

composer require mike42/escpos-php

```



If you haven't used `composer` before, you can read about it at [getcomposer.org](https://getcomposer.org/).



#### Requirements



This project has few hard dependencies:



- PHP 7.3 or newer.

- `json` extension, used to load bundled printer definitions (see [documentation](https://www.php.net/manual/en/book.json.php))

- `intl` extension, used for character encoding (see [documentation](https://www.php.net/manual/en/book.intl.php))

- `zlib` extension, used for de-compressing bundled resources (see [documentation](https://www.php.net/manual/en/book.zlib.php)).



It is also suggested that you install either `imagick` or `gd`, as these can be used to speed up image processing.



A number of optional extensions can be added to enable more specific features. These

are described in the "suggest" section of [composer.json](https://github.com/mike42/escpos-php/tree/master/composer.json).



### The 'Hello World' receipt



To make use of this driver, your server (where PHP is installed) must be able to communicate with your printer. Start by generating a simple receipt and sending it to your printer using the command-line.



```php

 text("Hello World!\n");

$printer -> cut();

$printer -> close();

```



Some examples are below for common interfaces.



Communicate with a printer with an Ethernet interface using `netcat`:



```bash

php hello-world.php | nc 10.x.x.x. 9100

```



A USB local printer connected with `usblp` on Linux has a device file (Includes USB-parallel interfaces):



```bash

php hello-world.php > /dev/usb/lp0

```



A computer installed into the local `cups` server is accessed through `lp` or `lpr`:



```bash

php hello-world.php > foo.txt

lpr -o raw -H localhost -P printer foo.txt

```



A local or networked printer on a Windows computer is mapped in to a file, and generally requires you to share the printer first:



```

php hello-world.php > foo.txt

net use LPT1 \\server\printer

copy foo.txt LPT1

del foo.txt

```



If you have troubles at this point, then you should consult your OS and printer system documentation to try to find a working print command.



### Using a PrintConnector



To print receipts from PHP, use the most applicable [PrintConnector](https://github.com/mike42/escpos-php/tree/master/src/Mike42/Escpos/PrintConnectors) for your setup. The connector simply provides the plumbing to get data to the printer.



For example, a `NetworkPrintConnector` accepts an IP address and port:



```php

use Mike42\Escpos\PrintConnectors\NetworkPrintConnector;

use Mike42\Escpos\Printer;

$connector = new NetworkPrintConnector("10.x.x.x", 9100);

$printer = new Printer($connector);

try {

    // ... Print stuff

} finally {

    $printer -> close();

}

```



While a serial printer might use:



```php

use Mike42\Escpos\PrintConnectors\FilePrintConnector;

use Mike42\Escpos\Printer;

$connector = new FilePrintConnector("/dev/ttyS0");

$printer = new Printer($connector);

```



For each OS/interface combination that's supported, there are examples in the compatibility section of how a `PrintConnector` would be constructed. If you can't get a `PrintConnector` to work, then be sure to include the working print command in your issue.



### Using a CapabilityProfile



Support for commands and code pages varies between printer vendors and models. By default, the driver will accept UTF-8, and output commands that are suitable for Epson TM-series printers.



When trying out a new brand of printer, it's a good idea to use the "simple" `CapabilityProfile`, which instructs the driver to avoid the use of advanced features (generally simpler image handling, ASCII-only text).



```php

use Mike42\Escpos\PrintConnectors\WindowsPrintConnector;

use Mike42\Escpos\CapabilityProfile;

$profile = CapabilityProfile::load("simple");

$connector = new WindowsPrintConnector("smb://computer/printer");

$printer = new Printer($connector, $profile);

```



As another example, Star-branded printers use different commands:



```php

use Mike42\Escpos\PrintConnectors\WindowsPrintConnector;

use Mike42\Escpos\CapabilityProfile;

$profile = CapabilityProfile::load("SP2000")

$connector = new WindowsPrintConnector("smb://computer/printer");

$printer = new Printer($connector, $profile);

```



For a list of available profiles, or to have support for your printer improved, please see the upstream [receipt-print-hq/escpos-printer-db](https://github.com/receipt-print-hq/escpos-printer-db) project.



### 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, CapabilityProfile $profile)

Construct new print object.



Parameters:

- `PrintConnector $connector`: The PrintConnector to send data to.

- `CapabilityProfile $profile` Supported features of this printer. If not set, the "default" CapabilityProfile 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, `Printer::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 `Printer::CUT_FULL` or `Printer::CUT_PARTIAL`. If not specified, `Printer::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. As an additional fallback, the `bitImageColumnFormat()` function is also provided.



### initialize()

Initialize printer. This resets formatting back to the defaults.



### pdf417Code($content, $width, $heightMultiplier, $dataColumnCount, $ec, $options)

Print a two-dimensional data code using the PDF417 standard.



Parameters:



- `string $content`: Text or numbers to store in the code

- `number $width`: Width of a module (pixel) in the printed code. Default is 3 dots.

- `number $heightMultiplier`: Multiplier for height of a module. Default is 3 times the width.

- `number $dataColumnCount`: Number of data columns to use. 0 (default) is to auto-calculate. Smaller numbers will result in a narrower code, making larger pixel sizes possible. Larger numbers require smaller pixel sizes.

- `real $ec`: Error correction ratio, from 0.01 to 4.00. Default is 0.10 (10%).

- `number $options`: Standard code `Printer::PDF417_STANDARD` with start/end bars, or truncated code `Printer::PDF417_TRUNCATED` with start bars only.



### 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 `Printer::QR_ECLEVEL_L` (default), `Printer::QR_ECLEVEL_M`, `Printer::QR_ECLEVEL_Q` or `Printer::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 `Printer::QR_MODEL_1`, `Printer::QR_MODEL_2` (default) or `Printer::QR_MICRO` (not supported by all printers).



### selectPrintMode($mode)

Select print mode(s).



Parameters:



- `int $mode`: The mode to use. Default is `Printer::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)

Parameters:



- `int $font`: The font to use. Must be either `Printer::FONT_A`, `Printer::FONT_B`, or `Printer::FONT_C`.



### setJustification($justification)

Select justification.



Parameters:



- `int $justification`: One of `Printer::JUSTIFY_LEFT`, `Printer::JUSTIFY_CENTER`, or `Printer::JUSTIFY_RIGHT`.



### setLineSpacing($height)



Set the height of the line.



Some printers will allow you to overlap lines with a smaller line feed.



Parameters:



- `int	$height`:	The height of each line, in dots. If not set, the printer will reset to its default line spacing.



### setPrintLeftMargin($margin)



Set print area left margin. Reset to default with `Printer::initialize()`.



Parameters:



- `int $margin`: The left margin to set on to the print area, in dots.



### setPrintWidth($width)
