I ended up using the print this plugin. It is EXTREMELY helpful. Thanks for your input.
For future users, here is how I did it:
I wanted ONLY the div tag layer7 to print. I put this text in an a href link on my single post page : PrintThisPage();
I then added this to the header.
function PrintThisPage()
{
var sOption=”toolbar=yes,location=no,directories=no,menubar=yes,”;
sOption+=”scrollbars=yes,width=750,height=600,left=100,top=25″;
var sWinHTML = document.getElementById(‘layer7’).innerHTML;
var winprint=window.open(“”,””,sOption);
winprint.document.open();
winprint.document.write(‘Title of your print preview’)
winprint.document.write(sWinHTML);
winprint.document.write(‘</body></html>’);
winprint.document.close();
winprint.focus();
}
