PAGE PRINTING
Many times you would
like to place a button on your webpage to print the content of that web page
via an actual printer. JavaScript helps you to implement this functionality
using the print function of window object.
The JavaScript print
function window.print() prints the
current web page when executed. You can call this function directly using the onclick event as shown in the following
example.
Example
Try the following example.
<head>
<script
type="text/javascript">
<!--
//-->
</script>
</head>
<body>
<form>
<input type="button"
value="Print" onclick="window.print()" />
</form>
</body>
Output
Print
Although it serves the
purpose of getting a printout, it is not a recommended way. A printer friendly
page is really just a page with text, no images, graphics, or advertising.
You can make a page printer friendly in the following ways:
1.
Make a copy of the page and leave out unwanted text and graphics, then
link to that printer friendly page from the original.
2.
If you do not want to keep an extra copy of a page, then you can mark
your printable text using proper comments like <!-- PRINT STARTS HERE
-->..... <!-- PRINT ENDS HERE --> and then you can use PERL or any
other script in the background to purge printable text and display for final
printing.
