A Pluginoven Test Site
Quick test of all the animation effects with Collapse-O-Matic v 1.8.3:
[expand title="slideToggle" animation_effect="slideToggle" duration="2000"]content[/expand][expand title="slideFade" animation_effect="slideFade"]content[/expand][expand title="fadeOnly" animation_effect="fadeOnly"]content[/expand]By default, WordPress will add loading=”lazy” to all img tags that have width and height attributes present. Normally this is desired. However, if a page has many images and is to be printed, often times images further down the page have not yet loaded, leaving large spaces as placeholders for when the user finally scrolls down that far and the image loads. Good for the web, bad for a PDF.
Print-Pro matic now offers the option to selectively turn-off this default loading="lazy" attribute for images for the entire site.
Below is a series of images with width and height defined. By default lazy-load should be enabled, but with the option turned on, the lazy-load is disabled, allowing the images to fully load on the page in preparation for printing.
The more advanced method is by using a custom print_view variable that turns off the lazy-load only when the print is triggered. To accomplish this, first add the following to the child-theme’s function.php file: (note, this is no longer required as of version 2.1.2)
function printpromatic_query_var( $vars ) {
$vars[] = 'print_view';
return $vars;
}
add_filter( 'query_vars', 'printpromatic_query_var' );
function print_with_no_lazy_load() {
if ( get_query_var( 'print_view' ) ) {
return false;
}
return true;
}
add_filter( 'wp_lazy_loading_enabled', 'print_with_no_lazy_load' );Next we add the print-me shortcode with a unique ID and url using the %print_view% placeholder:
[print-me id="donkey" url="%print_view%"/]Ad of version 2.1.2 there is a new option to add the print_view query var from the plugin options page–so no need to manually add this to the child-theme’s function.php file. This option will also add the print_with_no_lazy_load function. Version 2.1.2 also added a url_target attribute to allow the print version to load in the same tab:
[print-me id="monkey" url="%print_view%" url_target="_self"/]
This is a test on how to handle retroactively applying a collapse-expand feature to any element with a defined class.
The idea is to first have an element with a specific class that holds a heaping amount of content, like the one below:

Ok, that’s a lot of text. Now within collapse-pro-matic check for this class, if found append or prepend a trigger and then adjust the target to a defined minimum height.
This is something that would be applied to every element with the defined class, across all posts, future, present and past.
[expand title="Push me" swaptitle="Push" trigclass="noarrow my_button" tag="div"]this is the hidden content[/expand].my_button {
background-color: white;
color: black;
border-radius: 6px;
font-family: by;
padding: 5px;
width: 99px;
text-align: center;
border: 2px solid #98FB98; /* Green */
}
.my_button.colomat-hover{
background-color: #eb234c; /* red */
color: white;
text-align: center;
}This is a test to see if print-pro-matic can print an external URL:
[print-me url="https://docs.google.com/spreadsheets/d/e/2PACX-1vSC6kmo4lmXRBc7QHMmg_s2Dq4LBg0FHclszFjAhCW_wYo814nBWM_mQhAryRayPNdQJLCXw0gNVbPo/pubhtml"/]
There will be an issue with cross domain origin, however a url on the same domain can be printed:
[print-me url="https://spacedonkey.de/donkey/donkey-in-a-bucket/"/]This is a test to see how print-o-matic and print-pro-matic handle targeting a non-existing element:
[print-me target="#aintnosunshinewhenshesgone" /]No element? no problem… do nothing.
Now what happens if we have one element that does not exist in a list of elements:
[print-me target="non_elem, #printbox" /]As of print-o-matic version 2.0.1 the ability to use class to target a print element in external print triggers has been added. Basically it works the same as using the data-print_target attribute but instead uses a unique classname in the format of printtarget-<target_id>.
Create a target element. The element below is a div with an id of ‘my_print_target’:
<div id="my_print_target">This is the print target wrapped in a div with an element of 'my_print_target' as explained above</div>Add an external trigger using the new class-trigger method. We’ll use a simple button like so:
<button id="my_print_button" class="printomatic printtarget-#my_print_target">Print Trigger</button>
Like in the original example, we need to add the hidden print trigger using a print-me shortcode with the same id as our external trigger and a printstyle=”external” attribute:
[print-me id="my_print_button" printstyle="external"/]Quick test to demonstrate how to use the tag and css to control the look of a trigger.
[expand title="trigger" tag="h4"]hidden target content[/expand]
h4.collapseomatic {
color: blue;
}
