Meteor Cordova Print plugin - meteor

Question

I am developing a Point of sale (POS) for my store. And I am developing a Meteor app that will connect to the POS receipt printer. But as you know you cant simply use window.print().
I read but didnt understand the Meteor documentation about this, and I have several questions about it. (https://guide.meteor.com/mobile.html#using-plugins)
I have installed the katzer/cordova-plugin-printer (https://github.com/katzer/cordova-plugin-printer). And know here comes the questions.
1.- Once installed, I create a file outside the server and client folder and insert a statement such as
if (Meteor.isCordova) {
console.log("Printed only in mobile Cordova apps");
}
and then do I simply add the following line?
if (Meteor.isCordova) {
document.addEventListener('deviceready', function () {
// cordova.plugins.printer is now available
}, false);
}
2.- If this is correct, Do I create a Meteor Method in the server or in Meteor.isCordova? to call the following example.
var page = '<h1>Hello Document</h1>';
cordova.plugins.printer.print(page, 'Document.html');
3.- Should I use server side rendering to create the
var page = '<h1>Hello Document</h1>';
part.
Thank you

To answer your points:
Meteor.startup is run when the device or browser is ready (it's equivalent to what you are doing).
Create a method in the client code - Put the check in the button click method. Something like the code block at the end
Server side rendering won't apply as you are printing from the browser
if (Meteor.isCordova) {
Meteor.call("myPrintMethod",other-info);
} else {
alert("Sorry, I can only print from the device"
}
