Hi Asif,

This error is in the file "printer.js" which is a 3rd party plug-in. Unfortunately, third party plugins are out of scope of our support. You would need to fix the error or you could try to use this plugin with this error.

Asif,

Let's try to define your Cordova Plugin As A Cordova Module.
Let's look at org.apache.cordova.core.battery-status module in Appery.io.
A name in "clobbers" field of cordova_plugin.js is a name of reference to your module. For example, if we have such lines in cordova_plugin.js
pre{
"file": "plugins\com.phonegap.plugins.printer\www\printer.js",
"id": "com.phonegap.plugins.printer.Printer",
"clobbers": [
"Printer"
]
}/preAfter that, we should use such code to access the plugin: prePrinter.print(page);/pre

Hi Katya,
I have already made an entry of Printer plugin in cordova_plugin.js like you said.
And now when I am writing given below code
code
Printer.print(page)
/code

i m getting this error:
code
04-29 16:26:00.690: D/CordovaLog(6065): file:///android_asset/www/ipadscreen1.js: Line 369 : Uncaught TypeError: Object function () {

04-29 16:27:00.400: D/WebView(6065): loadUrlImpl: called
/code

I dont think there is any problem with the plugin, its just that i m not getting the way to use it with appery.
Can you please try to run the plugin once from my app. It would be a great help.

Hi Asif,

You should also "wrap" printer.js like a Cordova module.

Here is a pattern for such wrapping:
precordova.define("com.phonegap.plugins.printer.Printer", function(require, exports, module) {
var cordova = require('cordova'),
exec = require('cordova/exec');
........
//here paste a body of your plugin
..........
});/pre

Hi Katya,
Do you mean to say that my printer.js will look like this ::

code
cordova.define("com.phonegap.plugins.printer.Printer", function(require, exports, module) {
var cordova = require('cordova'),
exec = require('cordova/exec');
........
//here comes the whole content of printer.js ??
..........
});
/code

Hi Katya,
As you said i have wrapped printer.js and now i m calling print function as follows:

code
var page = document.body.innerHTML;
Printer.print(page);
/code
and now i m getting this error
code

Hello,

Correct cordova_plugins.js regarding printer plugin(pay attention to id)

code{
"file": "plugins\com.phonegap.plugins.printer\www\printer.js",
"id": "com.phonegap.plugins.printer.Printer",
"clobbers": [
"Printer"
]
}

/code
