print icon for page

Well a print page button is easy to get – as shortcode by this snippet in child-theme functions.php:

function print_button_shortcode($atts){
return '<a class="print-page" href="javascript:window.print()">Print This Page</a>';
}
add_shortcode( 'print_button', 'print_button_shortcode' );

class “print-page” is for styling that button – usage is via shortcode: [print_button]
Styling may contain an image than a Text to show

But: there are a lot of print plugins – where you can influence the parts of your page to print ( f.e. by class )
Print-O-Matic f.e.

you can use the shortcode whereever you like even in widgets or text-alb element
If it is in child-theme functions.php you can have comments in one-liner by //
or in more lines by /* your text */
or like i do for my snippets – give the function a meaningfull name – i think “print_button_shortcode” is unique enough to remember what function it is.

f.e.

// shortcode for print page button
function print_button_shortcode($atts){
return '<a class="print-page" href="javascript:window.print()">Print This Page</a>';
}
add_shortcode( 'print_button', 'print_button_shortcode' );
