Print a web page content using JavaScript

Are you aware of printing the content of a web page via an actual printer using JavaScript? Don’t get confuse!

JavaScript can help you to implement print functionality using a print function of window object. This works on all modern browsers, so this can be a valid substitute inside a browser where toolbar is disabled.

Here is the syntax to print using JavaScript:

window.print()

The JavaScript print() method prints the contents of a current window.
This opens a Print Dialog Box, which tells the user to select desired printing options.

Browser Support: Chrome, Internet Explorer, Firefox, Safari, Opera.

You can use this function using the onclick event as shown in the example below:

<html>
<head>
</head>
<body>
<form>
<input type="button" value="Print" >
Always make sure that your visitor’s browser have JavaScript enabled before providing them a button that works using JavaScript.

If this is disabled then, saving them frustration of clicking a same button which does absolutely nothing:
 
<script language="JavaScript">
if (window.print) {
document.write('<form><input type="button" value="Print" >
If you do not like the functionality about print using JavaScript on a web page, then you can use the browser’s default toolbar to get print a web page like below:

File >  Print > Click OK  button.
