Javascript print function

Can anyone help integrate jbirk's code? It works fine on it's own but i need to use my own home made button and do an if then in my javascript to accomodate n4 and ie4 Mac&Pc.

my original question:
I have made a print button in a toolbar-less window, this works perfectly in Netscape 4 for the mac and pc, however not in IE 4 for the mac or pc. Anyone know a a different print call I can use to make this work in both browsers? Thanks you so ever dearly much!!!!-n

    Here's what I do now. (Body being the frame I want the button click to print out.
    <script language="javascript">

    function runPrint()
    {
    parent.body.print();

    }
    </script>

    ------

    <td align="left" valign="top" cellspacing="0" cellpadding="0" border="0" nowrap>
    <a href="top.html"
    onClick="runPrint();"
    onMouseDown="pushBtnn('print','../images/print_btn_d.gif');"
    onMouseUp="pushBtnn('print','../images/print_btn.gif');"
    onMouseOver="pushBtnn('print','../images/print_btn_o.gif');" onMouseOut="pushBtnn('print','../images/print_btn.gif');return true"><img
    src="../images/print_btn.gif" border="0" name='print'  hspace="0" vspace="0"></a></td>

Jbirk's helpful answer:
To print in IE4 you need VBScript.  I don't know any VBScript, but I have the code to do this.  I just won't know how to modify it or anything.  Anyway, here's the code:

    <object id=WBControl width=0 height=0
    classid=CLSID:8856F961-340A-11D0-A96B-00C04FD705A2></object>
    <SCRIPT LANGUAGE=VBScript><!-- //
    Sub VBPrint() On Error Resume Next
    WBControl.ExecWB 6,1
    End Sub
    // --></SCRIPT>
    <SCRIPT LANGUAGE=JavaScript><!-- //
    if (navigator.appName.indexOf('Microsoft') !=-1)
      document.write('<FORM><INPUT TYPE="BUTTON" ONCLICK="VBPrint()" value="Print"></FORM>');
    else if (self.print)
      document.write('<FORM><INPUT TYPE="BUTTON" ONCLICK="self.print()" value="Print"></FORM>');
    // --></SCRIPT>
    That produces a generic button which will print when you click on it.  You can of course modify your scripts to cause the print to occur on
    whatever the vent is that you want it to occur on.

    Good Luck!
