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.
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).

/*
 * 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.

Note: All required CSS rules needs to be included as well.

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

// Pass the HTML
window.plugin.printer.print(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.

window.plugin.printer.isServiceAvailable(
    function (isAvailable, installedAppIds) {
        alert('The following print apps are installed on your device: ' + installedAppIds.join(', '));
    }
);

Specify printing app on Android

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.

window.plugin.printer.print(page, { appId: 'epson.print' });

Quirks

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.

<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.
