How should I name print templates?
Print templates should be prefixed with wpf and follow WordPress template conventions from there. To use one template for all contexts unless otherwise specified, name your template wpf.php.
For both built-in and custom post types, wpf-[post type name].php will be used for that post type. To use a template for a single post type object, name your template wpf-[post type name]-[slug].php.
For custom taxonomies, follow the naming conventions for post types.
Similarly, wpf-home.php will load that template for the front page of your site.
The plugin also includes a default template that may suit many needs.
How do I add a print link to my templates?
wpf_the_print_linkwill add a link to the print-friendly version of whatever page it appears on. This function accepts the following arguments:
- $page_link: Set to true to add a link to the current page in a paged post in addition a to a link for the entire post.
- $link_text: Set to text that should appear for the print link. Defaults to Print this post.
- $class: Specifies the CSS class for the print link. Defaults to print_link.
- $page_link_separator: If $page_link is true, specifies what separator will appear between the print link for the entire post and the print link for the current page of the post.
- $page_link_text: If $page_link is true, specifies what text will appear for the print link for the current page. Defaults to Print this page.
- $link_target: If set to “new”, print links will open in a new window.

(Not recommended in many cases!), interfere with WP Print Friendly’s ability to display print templates. Both must be disabled, and the site’s rewrite rules regenerated (by visiting Options > Permalinks and clicking Save Changes), for WP Print Friendly to function.
