## Release Notes ##
#### Version 0.2.1 ####
- Support for callback scopes

#### Version 0.2.0 (11.08.2013) ####
- Added iOS support<br>
  *Based on the Print iOS plugin made by* ***Randy McMillan***

## Using the plugin ##
The plugin creates the object ```window.plugin.printer``` with two methods:

### isServiceAvailable() ###
Printing is only available on devices capable of multi-tasking (iPhone 3GS, iPhone 4 etc.) running iOS 4.2 or later. You can use this function to hide print functionality from users who will be unable to use it.<br>
Function takes a callback function, passed to which is a boolean property. Optionally you can assign the scope in which the callback will be executed as a second parameter (default to *window*).

```javascript
/*
 * Find out if printing is available. Use this for showing/hiding print buttons.
 */
window.plugin.printer.isServiceAvailable(
    function (isAvailable) {
        alert(isavailable ? 'Service is available' : 'Service NOT available');
    }
);
```

### print() ###
Function takes an html string and (optionally) a callback function. Optionally you can assign the scope in which the callback will be executed as a third parameter (default to *window*).

```javascript
// Get HTML string
var page = document.body.innerHTML;

/*
 * Pass an HTML and - optionally - a callback function.
 */
window.plugin.printer.print(page, function (success, available, error) {

}, this);
```

#### Testing in the iOS Simulator ####
There's no need to waste lots of paper when testing - if you're using the iOS simulator, select File->Open Printer Simulator to open some dummy printers (print outs will appear as PDF files).

#### Adding Page Breaks to Printouts ####
Use the 'page-break-before' property to specify a page break, e.g.

```html
<p>
First page.
</p>

<p style="page-break-before: always">
Second page.
</p>
```

Note: you will need to add an extra top margin to new pages.
