What is the code for adding the Print icon and functionality to another component in Joomla?

Question

So basically, the print functionality does not work by default in Joomla but I've fixed that with some code modifications. However, this functionality is only available in the articles. I have a blog component and I need to make the print button available in the blog entries too

Does anyone knows the code for this? Or knows the files I need to edit?

Many Thanks in advance.

The print functionality is essentially loading your page with &tmpl=component added to the URL. This request variable tells Joomla to load the page, but only with the output from <jdoc:include type="component" />. The modules and the rest of the template get hidden.

For the icon, the com_content component is actually using its own helper library in components/com_content/helpers/icon.php. You're best off using line 145 from that file:

JHTML::_('image.site', 'printButton.png', '/images/M_images/', NULL, NULL, JText::_( 'Print' ) );

This will generate the <img /> tag for the printer icon.
