PrinterJS

A module created to help with printing elements on an html page in an easy and intuative way.

Originally forked from print-html-element continue development.

This fork's main improvement is the use of typescript over vanilla js. I will continue to itterate over this to add the intended 'future functionality' of the original author.

Installation

Print HTML Element is available on both NPM and Bower.

npm install printerjs

yarn install printerjs

Usage

Include

In a CommonJS module system via Browserify or Webpack

    var PHE = require("printerjs");

or (ES)

    import printer from "printerjs";

Good old-fashioned way

    <script type="text/javascript" src="printer.js"></script> 

    // Alias global variable printHtmlElement for purposes of example
    var printer = ElementPrinter;

Examples

View examples here

    printer.printElement( document.getElementById('toPrint') );
    printer.printHtml('<h1>Let\'s print this h1</h1>');
 
    printer.printHtml('<h1>Let\'s print this h1</h1>', {templateString: '<header>I\'m part of the template header</header>{{printBody}}<footer>I\'m part of the template footer</footer>'});

An HTML class pe-body is also added to the body of the print area which can be used as an additional style hook (on top of the regular print media query/stylesheet)

Options and methods supported

    opts = {
        printMode: string;
        pageTitle: string;
        templateString: string;
        popupProperties: string;
        closePopup: boolean;
        stylesheets: string | string[];
        styles: string | string[];
    };
 
    printer.printElement( elem, opts ); // Prints a DOM Element
    printer.printHtml( str, opts ); // Prints an HTML string

• printMode determines which method is used to print. As a hidden iframe (default), or popup window
• pageTitle sets the printed page title (defaults to blank)
• templateString allows you to define a template that the html will be printed within.
  • Use {{printBody}} within the template to signify where the HTML should be injected
• popupProperties set the window features (such as menubar, scrollbars, etc. in popup mode
• closePopup determines if the popup should automatically close after trying to print. This is useful for mobile and automatic print on unsupported browsers
• stylesheets overrides parsed link tags and instead injects link tags with hrefs specified as either a single string or array of strings
• styles overrides parsed style tags and instead injects style blocks specified as either a single string or array of strings

Next Feature

• Promise/callback support

Possible future features

• Integrate a template system (such as handlebars)
• Support multiple and/or custom template variables
• Support for multiple elements/HTML strings
