Do you want to have a button on a webpage that allows the user to print only a portion of the content on the webpage? One approach is to setup your webpage so that the "print" button will only print the content that you put within a "<div>" tag.
NOTE: another approach to printing only part of a webpage is shown here:
Print only a portion of a web page
Step 1 - Put this Javascript in your webpage:
<script>
function printDiv(divName) {
var printContents = document.getElementById(divName).innerHTML;
var originalContents = document.body.innerHTML;
document.body.innerHTML = printContents;
window.print();
document.body.innerHTML = originalContents;
}
</script>
Step 2 - Put a div tag around part of your webpage with an ID:
<div id=example>
content you want to print here....
</div>
Step 3 - Put a button inside your div tag so a user can print the div tag
<input type='button' value='Print This Only' onclick='printDiv(example);'/>"
