How to print specific part of a web page in javascript

It is a comman feature to take print out of a web page contents or some particular section of a web page. Such features are generally used in admin card print out, examination forms, some important notifications, etc. In this article, we provide you a simple way to take print of a specific section contents or full page contents of an HTML web page using Javascript. Javascript is used to make most interactive and dynamic web pages. It is most widely used because it can be easily integrated with HTML and almost all popular programming languages.

For this, we have created an HTML page and divide the full page contents in three sections. Each section contains print button to print that section. The first print button prints the full page content.

<html>
    <head>
        <style>
            h1{ display: inline;}
            #container { width: 500px; margin: 0 auto; }
            img { float: right;}
            .section { border: 2px solid #0197CA;
             border-radius: 3px; margin: 10px 0; padding: 5px;}
        </style>
        <script type="text/javascript">
            function printSection(el){
                var getFullContent = document.body.innerHTML;
                var printsection = document.getElementById(el).innerHTML;
                document.body.innerHTML = printsection;
                window.print();
                document.body.innerHTML = getFullContent;
            }
        </script>
    </head>
    <body>
    <h1>Content</h1>
	<a onclick="printSection('container')">
	<img title="Print Full Page Content" src="images/printicon.png" alt="Printicon" />
	</a>
   <div id="container">
   <div class="section">
      For this we are using HTML and simple javascript code.<br /><br />
      <h1>First Section</h2>
      <a onclick="printSection('section1')">
	   <img title="Print First Section" src="images/printicon.png" alt="" />
	  </a>
      <div id="section1">
	  Lorem Ipsum is simply dummy text of the printing and typesetting industry.
	  Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, 
	  when an unknown printer took a galley of type and scrambled it to make a type specimen book. 
	  It has survived not only five centuries, but also the leap into electronic typesetting,
          remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets
          containing Lorem Ipsum passages, and more recently with desktop publishing software 
          like Aldus PageMaker including versions of Lorem Ipsum.</div>
   </div>
   <br /><br />
   <div class="section">
      <h1>Second Section</h1>
      <a onclick="printSection('section2')">
	    <img title="Print Second Section" src="images/printicon.png" alt="" />
	  </a>
      <div id="section2">Contrary to popular belief, Lorem Ipsum is not simply random text.
	  It has roots in a piece of classical Latin literature from 45 BC, making it over 
	  2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in
	  Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem
	  Ipsum passage, and going through the cites of the word in classical literature, 
	  discovered the undoubtable source. Lorem Ipsum comes from sections 1.10.32 and 1.10.33 of
	  "de Finibus Bonorum et Malorum" (The Extremes of Good and Evil) by Cicero, written in 45 BC.
	  This book is a treatise on the theory of ethics, very popular during the Renaissance. 
	  The first line of Lorem Ipsum, "Lorem ipsum dolor sit amet..", comes from a line in section 1.10.32.
	  </div>
   </div>
   <br /><br />
   <div class="section">
      <h1>Third Section</h1>
      <a onclick="printSection('section3')">
	  <img title="Print Third Section" src="images/printicon.png" alt="" />
	  </a>
      <div id="section3">It is a long established fact that a reader will be distracted by 
	  the readable content of a page when looking at its layout. The point of using Lorem
	  Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using
	  'Content here, content here', making it look like readable English. Many desktop publishing 
	  packages and web page editors now use Lorem Ipsum as their default model text, and a search 
	  for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have 
	  evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).
