SAMPLE APP 👉

Cordova Print Plugin npm version Build Status

Plugin for the Cordova framework to print HTML from iOS, Android and Windows Universal apps.

             

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.

See Drawing and Printing Guide for iOS for detailed informations.

About Android Printing Framework

Starting with KitKat, 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.
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.

See Building Apps with Multimedia for Android for detailed informations.

Print content

/**

 *      if latter, innerHTML is used to get the content
 * @param {Object} options

 * @param {Function} callback
 *      An optional callback function
 * @param {Object} scope
 *      An optional scope of the callback
 *      Defaults to: window
