Print button for Custom list with Infopath form

Scenario:
We wanted to extend the Ribbon to have a Print button for Custom list with Infopath form.

While I found so many articles to extend Ribbon UI, most of them are for a regular list / library. In SP2010, now we do have an option to use a Infopath for a custom list which uses a brand new Ribbon Tab/Grouping and I found nothing much on Web.

Solution:
Use the following Element manifest.

Code:

<?xml version="1.0" encoding="utf-8"?>
<Elements xmlns="http://schemas.microsoft.com/sharepoint/">
 <CustomAction
 Id="InfopathformPrintButton"
 Location="CommandUI.Ribbon" Rights="ViewListItems">
  <CommandUIExtension>
   <CommandUIDefinitions>
    <CommandUIDefinition
     Location="Ribbon.Tabs.InfoPathListDisplayTab.Manage.Controls._children">
     <Button Id="Ribbon.Tabs.InfoPathListDisplayTab.Manage.Controls.Print"
      Command="CallPrint"
      Sequence="1"
      Description="Print the infopath form"
       Image16by16="/_layouts/images/placeholder32x32.png"
       Image32by32="/_layouts/images/placeholder32x32.png"
      LabelText="Print"
      TemplateAlias="o1"/>
    </CommandUIDefinition>
   </CommandUIDefinitions>
   <CommandUIHandlers>
    <CommandUIHandler
     Command="CallPrint"
     CommandAction="javascript:function processPrint(){window.print()};processPrint();" />
   </CommandUIHandlers>
  </CommandUIExtension>
 </CustomAction>
</Elements>
