- If you use any other printer with this code, please [let us know](https://github.com/mike42/escpos-php/issues/new) so that it can be added to the list.
- ## Basic usage
- ### Include the library
- #### Composer
- If you are using composer, then add `mike42/escpos-php` as a dependency:
- ```bash
- composer require mike42/escpos-php
- ```
- In this case, you would include composer's auto-loader at the top of your source files:
- ```php
- <?php
- require __DIR__ . '/vendor/autoload.php';
- ```
- #### Manually
- If you don't have composer available, then simply download the code and include `autoload.php`:
- ```bash
- git clone https://github.com/mike42/escpos-php vendor/mike42/escpos-php
- ```
- ```php
- <?php
- require __DIR__ . '/vendor/mike42/escpos-php/autoload.php';
- ```
- #### Requirements
- To maintain compatibility with as many systems as possible, this driver has few
- hard dependencies:
- - PHP 5.4 or above.
- - `mbstring` extension, since the driver accepts UTF-8 encoding.
- It is also suggested that you install either `imagick` or `gd`, so that you can
- print images.
- A number of optional packages 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
- <?php
- /* Call this file 'hello-world.php' */
- require __DIR__ . '/vendor/autoload.php';
- use Mike42\Escpos\PrintConnectors\FilePrintConnector;
- use Mike42\Escpos\Printer;
- $connector = new FilePrintConnector("php://stdout");
- $printer = new Printer($connector);
- $printer -> 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 bug.
- ### 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
- <?php
- $img = EscposImage::load("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. 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).
