PDF Printing

Print.js was primarily written to help us print PDF files directly within our apps, without leaving the interface, and no use of embeds. For unique situations where there is no need for users to open or download the PDF files, and instead, they just need to print them.

One scenario where this is useful, for example, is when users request to print reports that are generated on the server side. These reports are sent back as PDF files. There is no need to open these files before printing them. Print.js offers a quick way to print these files within our apps.

PDF files must be served from the same domain as your app is hosted under. Print.js uses iframe to load files before printing them, therefore, it is limited by the Same Origin Policy. This helps preventing Cross-site scripting (XSS) attacks.

Example

Add a button to print a PDF file located on your hosting server:


 <button type="button" onclick="printJS('docs/printjs.pdf')">
    Print PDF
 </button>

Result:

For large files, you can show a message to the user when loading files. 


 <button type="button" onclick="printJS({printable:'docs/xx_large_printjs.pdf', type:'pdf', showModal:true})">
    Print PDF with Message
 </button>

Result:

The library supports base64 PDF printing: 


 <button type="button" onclick="printJS({printable: base64, type: 'pdf', base64: true})">
    Print PDF with Message
 </button>

Result:

HTML Printing

Sometimes we just want to print selected parts of a HTML page, and that can be tricky. With Print.js, we can easily pass the id of the element that we want to print. The element can be of any tag, as long it has a unique id. The library will try to print it very close to how it looks on screen, and at the same time, it will create a printer friendly format for it.

Example

Add a print button to a HTML form:


 <form method="post" action="#" id="printJS-form">
    ...
 </form>

 <button type="button" onclick="printJS('printJS-form', 'html')">
    Print Form
 </button>

Result:

Name:
Email:
Message:

Print.js accepts an object with arguments. Let's print the form again, but now we will add a header to the page:


 <button type="button" onclick="printJS({ printable: 'printJS-form', type: 'html', header: 'PrintJS - Form Element Selection' })">
    Print Form with Header
 </button>

Result:

The "new" in the user's query likely alludes to the subtle modernization efforts that version 74 introduces. Unlike the stark, almost industrial interfaces of its predecessors, recent iterations of Opera Mini have adopted a more fluid, Material Design-inspired aesthetic. Version 74 refines this, offering a customizable start page with news feeds and a cleaner, ad-blocking interface. The addition of a built-in file manager and a robust download manager signals a shift: the browser is no longer just a window to the web, but a utilitarian toolbox for the mobile user. It attempts to be the "everyman’s browser," capable of handling low-end hardware while still offering features like a night mode and offline reading that high-end users demand.

The current iteration of Opera Mini on Google Play includes:

In the fast-paced world of mobile browsers, giants like Google Chrome, Samsung Internet, and Mozilla Firefox dominate the headlines. However, there is a tenacious veteran that continues to evolve, specifically targeting users who crave speed, data savings, and reliability on modest hardware or expensive data plans: .

JSON Printing

A simple and quick way to print dynamic data or array of javascript objects.

Example

We have the following data set in our javascript code. This would probably come from an AJAX call to a server API:


 someJSONdata = [
    {
       name: 'John Doe',
       email: 'john@doe.com',
       phone: '111-111-1111'
    },
    {
       name: 'Barry Allen',
       email: 'barry@flash.com',
       phone: '222-222-2222'
    },
    {
       name: 'Cool Dude',
       email: 'cool@dude.com',
       phone: '333-333-3333'
    }
 ]

We can pass it to Print.js:


 <button type="button" onclick="printJS({printable: someJSONdata, properties: ['name', 'email', 'phone'], type: 'json'})">
    Print JSON Data
 </button>

Result:

We can style the data grid by passing some custom css:


 <button type="button" onclick="printJS({
	    printable: someJSONdata,
	    properties: ['name', 'email', 'phone'],
	    type: 'json',
	    gridHeaderStyle: 'color: red;  border: 2px solid #3971A5;',
	    gridStyle: 'border: 2px solid #3971A5;'
	})">
    Print JSON Data
 </button>

Result:

We can customize the table header text sending an object array


 <button type="button" onclick="printJS({
	    printable: someJSONdata,
	    properties: [
		{ field: 'name', displayName: 'Full Name'},
		{ field: 'email', displayName: 'E-mail'},
		{ field: 'phone', displayName: 'Phone'}
	    ],
	    type: 'json'
        })">
    Print with custom table header text
 </button>

Result:

JSON, HTML and Image print can receive a raw HTML header:


<button type="button" onclick="printJS({
		printable: someJSONdata,
		type: 'json',
		properties: ['name', 'email', 'phone'],
		header: '<h3 class="custom-h3">My custom header</h3>',
		style: '.custom-h3 { color: red; }'
	  })">
	Print header raw html
</button>
