Print-O-Matic and WordPress Charts

Here is an example of using Print-O-Matic to print a WordPress Chart using wp-charts.

[print-me target="%prev%"/]

Works in 2.0.
Pre 2.0:
It seems we need to wrap the chart shortcode in a div so we can target that div and include it’s related javascript.
Still not. maybe we also need to include the chart js on the page?
Nope. It seems the HTML Canvas element is not cloning it’s content that was generated by the javascript… hmmm.

Ultimate Print-O-Matic Form Elements Test

This is a test for printing various forms using Print-O-Matic and Print-Pro-Matic plugins.

Standard HTML Form

This is some text inside the target div


Boy
Girl
Dog

OK, for some reason the current theme (Twenty-Seventeen) forces all form elements to display:none when printed. This works on other themes.
[print-me title="Print Standard HTML Form" alt="Print the HTML form" target="#html_form, #texter"/]
Print Standard HTML Form

Print-O-Matic External Buttons

this is a test element


As of version 1.6.7c we introduced a new printstyle value ‘external’ for Print-O-Matic. Now it is possible to create an external button to trigger a print in a less-hacky way. Here is an example of this works: To print the following div with an id of ‘print_me_please’:

<div id="print_me_please">This is our target print element</div>

First we create a kind of roll-your-own print trigger. The details that must be included are:

  1. a unique id
  2. a print-o-matic class such as printomatic or printomatictext
  3. a data-print_target attribute

For example:

<button id="my_print_button" class="printomatic" data-print_target="#print_me_please">Print Trigger</button>

Which will output:

The final thing we need to do is include a hidden print trigger using a print-me shortcode with the same id as our external trigger and the new external printstyle attribute. This shortcode must be placed someplace on the same page, and will load in all the required scripts and settings to make the print trigger work correctly.

[print-me id="my_print_button" printstyle="external"/]


This shortcode will not output anything to the page.
That’s it. You are done! Let us know on the WordPress Support Forum if you require any further assistance.

Print-Pro-Matic Inject Logo Before Print Element

This is a quick test to inject a logo at the top of a print-pro-matic page using only css.
In this case, the print element has a class of #post-2182 and it is targeted as normal:

[print-me target="#post-2182"]

However now we add the following css to the our theme:

@media print {
   #post-2182::before {
      content: url(https://spacedonkey.de/wp-content/uploads/2012/09/ninja_turtles-300x223.jpg);
   }
}

This will place the logo in the ::before pseudo class of the targeted print element on the print page. however if the images does NOT exist on the page then it will not have enough time to load before print is triggered. Let’s try it out:

[print-me target="#post-2182" pause_before_print="500"/]

Probably now image right? Now click the print icon again. Image. How to solve this?

Guess we need to use top_html and bottom_html to define custom content and provide a bit of pause_before_print time.

Wonky Submit & Print-O-Matic Button

This is a Dr. Frankenstein experiment with Contact Form 7’s Submit button and the Print-O-Matic Print button. In theory, when submitting this form, the form should also also force-launch the print dialogue. Years of working in UI tells us NOT do this, but hey, people still have music playing on page load, so what do we know.

[contact-form-7 id="1018" title="SubPrint"/]

To cross-breed the Submit button with the print-o-matic print trigger, use the roll-your-own method as follows:

  1. create a cf7 submit/print button by assigning it a unique ID (in this case subprint) and a class of printomatic.
    [submit id:subprint class:printomatic]

  2. manually insert a hidden input that has the ID of “target-” and a value of the target you wish to print.
    <input type="hidden" id="target-subprint" value=".wpcf7-form" />

  3. be sure the ‘Shortcode Loads Scripts’ checkbox is NOT checked in the plugins options page.

Update: This is no longer supported in the current version of print-o-matic. Here is how to implement this solution with print-pro-matic.
