Javascript print overview

The print() method provides a scripted way of sending the window or a frame from a frameset to the printer.In all cases,the Print dialog box appears for the user to make the typical printer choices when printing manually.This presents a rogue print() command from tying up a printer without the user's permission

Using window.print() to print a document

The Javascript print() function performs the same operation as the IE or NN print option .The Javascript print function will send the contents of the page to the user's printer.See below example code:

<form>
<input type="button" value="Print This Page" onClick="window.print()" />
</form>

If you click print() button your computer will handle the printing functions.

Onload Javascript  print ()

If you want to be annoying, off of just about any Event Handler like this, adding onLoad will force a print request when the page loads:

onLoad="window.print()"

Javascript print link example

<a href="javascript:window.print()">Print The Page</a>

Using window.print() to print a frame document

In IE5,the print dialog box gives the user the chocie of printing hust frame or all of the frames.Make sure that the print() method is invoked for the desired frame when you want only that frame to print.The browser defaults to printing just that frame

function printFrames(n){
   parent.frames[n++].print()
      if(n<parent.frames.length) {
           setTimeout("printFrames("+n+")",5000)
     }
    }
