Cordova Printer-Plugin
======================
A bunch of printing plugins for Cordova 3.x.x <p align="right">
<b><a href="#">master</a></b>

Cordova Print Plugin
====================
[Cordova][cordova] plugin to print HTML documents using [__AirPrint__][AirPrint] and [__Android Printing Framework__][APF].
:bangbang:&nbsp;__Choose the right branch for you!__&nbsp;:bangbang:
The plugin provides multiple branches to support different printer types and android versions while _AirPrint_ is supported with each one.
- [master Branch][master_branch] for iOS and Android >= 4.4 (>= v0.7.x)
- [google-cloud-print Branch][google-cloud-print_branch] for Android <= 4.3 (~> v0.6.x)
- __Deprecated__ [network-printer Branch][network-printer_branch] for Android <= 4.3 (<= v0.5.x)
### About Apple AirPrint
AirPrint is an Apple™ technology that helps you create full-quality printed output without the need to download or install drivers. AirPrint is built in to many printer models from most popular printer manufacturers. Just select an AirPrint printer on your local network to print from your favorite iOS or OS X app.<br>
AirPrint printers are available for these devices when using the latest version of iOS available for them:
- iPad (all models)
- iPhone (3GS or later)
- iPod touch (3rd generation or later)
<img src="http://static1.businessinsider.com/image/4cf67b8149e2aeb00b020000/only-12-printers-work-with-apples-airprint-heres-the-list.jpg" />
### Android Printing Framework
Printing in __Android 4.4__ and later is provided by the Printing framework. By default, most Android devices have print service plugins installed to enable printing using the Google Cloud Print and Google Drive services. Print service plugins from other printer manufactures are available through the App Store though the Google Cloud Print service plugin can also be used to print from an Android device to just about any printer type and model.<br>
In addition to supporting physical printers, it is also possible to save printed output to your Google Drive account or locally as a PDF file on the Android device.
<img src="http://androidtopnews.com/wp-content/uploads/2013/10/46888__android-4.4-kitkat-official-4.jpg" />
### Supported Printers
Printing is supported on AirPrint- and Google Cloud Print-enabled printers or from Android devices to compatible network printers over Wi-Fi. The following pages contain more information:
- AirPrint-enabled printers: http://www.apple.com/ipad/features/airprint.html

## Example ## Examples
The following exmaple demonstrates how to print out the whole HTML page. __NOTE:__ All CSS rules needs to be embedded or accessible via absolute URLs in order to print out HTML encoded content.
#### 1. Print the whole HTML page
```javascript ```javascript
// Get the content // URI for the index.html
var page = document.body; var page = location.href;
// Pass to the printer cordova.plugins.printer.print(page, 'Document.html', function () {
window.plugin.printer.print(page); alert('printing finished or canceled')
});
``` ```
#### 2. Print the content from a part of the page
## Platform specifics
### Get all available printing apps on Android
The callback function will be called with a second argument which is an array, indicating which printer apps are available for printing.
```javascript ```javascript
window.plugin.printer.isServiceAvailable( // Either a DOM node or a string
function (isAvailable, installedAppIds) { var page = document.getElementById('legal-notice');
alert('The following print apps are installed on your device: ' + installedAppIds.join(', '));
} cordova.plugins.printer.print(page, 'Document.html', function () {
); alert('printing finished or canceled')
});
``` ```
### Specify printing app on Android #### 3. Print custom specific content
An App-ID can be assigned as a platform configuration to indicate which 3rd party printing app shall be used. Otherwise the first found application will be used.
```javascript ```javascript
window.plugin.printer.print(page, { appId: 'epson.print' }); // Either a DOM node or a string
var page = '<h1>Hello Document</h1>';
cordova.plugins.printer.print(page, 'Document.html', function () {
alert('printing finished or canceled')
});
``` ```
#### 4. Print remote web page
```javascript
cordova.plugins.printer.print('http://blackberry.de', 'BB!!!', function () {
alert('printing finished or canceled')
});
```
#### 5. Adjust the page
```javascript
cordova.plugins.printer.print('123', { name:'Document.html', landscape:true }, function () {
alert('printing finished or canceled')
});
```
