Javascript Event Handler for Print

I am trying to alter style at print-time:

Is there an event in javascript that you can listen for for when file>>print is called? What is it? Also - is there a handler for when printing is finished? What is it?

or if there is a better way to do this with some other means, such as style sheets, how do you do that?

From stackoverflow

• IE has onbeforeprint and onafterprint

• In IE there are the nonstandard window.onBeforePrint() and window.onAfterPrint() event listeners. There isn't a non-IE way to do it that I know of, however.

  What kinds of changes are you trying to make? It's possible that your problem could be solved by specifying different rules for your print stylesheet.

• Different Style Sheets

  You can specify a different stylesheet for printing.

  <link rel="stylesheet" type="text/css" media="print" href="print.css" />
  <link rel="stylesheet" type="text/css" media="screen" href="main.css" />
  

  One Style Sheet

  As kodecraft mentioned, you can also put the styles into the same file by using the @media block.

  @media print {
      div.box {
          width:100px;
      }
  }
  
  @media screen {
      div.box {
          width:400px;
      }
  }
  

• We also found that you can do a print-only style with the following:

  <style type="text/css">
  @media print {
      div
      {
          overflow:visible;
      }    
  }
  </style>
