We can easly add print functionality on SharePoint Page. Just add following Javascript on the page (you can use HTML Form Webpart for adding javascript).
In Javascript i have used WebPartElementID="onetIDListForm" ; which is SharePoint Default ID of the Main contents.
JavaScript:
<script type="text/javascript" language="JavaScript">
//Controls which Web Part or zone to print 'TD ID'
var WebPartElementID = "onetIDListForm"; //SharePoint Main Content ID
//Function to print Web Part
function PrintArea()
{
var bolWebPartFound = false;
if (document.getElementById != null)
{
//Create html to print in new window
var PrintingHTML = '<HTML>\n<HEAD>\n';
//Take data from Head Tag
PrintingHTML += document.getElementsByTagName('head')[0].innerHTML;
PrintingHTML += '\n</HEAD>\n<BODY class="printSQS">\n';
var WebPartData = document.getElementById(WebPartElementID);
if (WebPartData != null)
{
PrintingHTML += WebPartData.innerHTML;
bolWebPartFound = true;
}
else
{
bolWebPartFound = false;
alert ('Cannot Find Web Part');
}
}
PrintingHTML += '\n</BODY>\n</HTML>';
//Open new window to print
if (bolWebPartFound)
{
var PrintingWindow = window.open("","PrintWebPart",
"toolbar,width=800,height=600,scrollbars,resizable,menubar");
PrintingWindow.document.open();
PrintingWindow.document.write(PrintingHTML);
PrintingWindow.document.close();
// Open Print Window
PrintingWindow.print();
}
}
</script>
PrintingHTML += '\n</HEAD>\n<BODY class="printSQS">\n';
var WebPartData = document.getElementById(WebPartElementID);
if (WebPartData != null)
{
PrintingHTML += WebPartData.innerHTML;
bolWebPartFound = true;
}
else
{
bolWebPartFound = false;
alert ('Cannot Find Web Part');
}
}
PrintingHTML += '\n</BODY>\n</HTML>';
//Open new window to print
if (bolWebPartFound)
{
var PrintingWindow = window.open("","PrintWebPart",
"toolbar,width=800,height=600,scrollbars,resizable,menubar");
PrintingWindow.document.open();
PrintingWindow.document.write(PrintingHTML);
PrintingWindow.document.close();
// Open Print Window
PrintingWindow.print();
}
}
</script>
HTML Code:
<input type="button" value="Print" onclick="javascript:void(PrintArea());return false;__doPostBack('btPrint','')" />
<a href="#" onclick="javascript:void(PrintArea());return false;__doPostBack('btPrint','')" ><img src="/sites/aaa/PublishingImages/print.gif" border="0" complete="complete"/></a>
