Export a single PDF with all posts, or custom post types.

<blockquote>
IMPORTANT This plugin requires at least 512MB of free RAM available, or it will timeout / return an error.
</blockquote>
This plugin is NOT recommended for people with no tech knowledge. 
The PDF layout/design is VERY basic and will require html/css/php technical knowledge to customize. 
Read more about this below.
<h4>The Basics</h4>
The plugin checks if a pdf already exists with the same date (ddMonyear), if yes, the existing pdf will be served, otherwise a new will be generated. Since the PDF generation uses up a lot of resources, this will prevent too many runs of the plugin and the crashing of your server. 
Check the example below or the FAQ for ways to force the PDF generation anyway.
Depending on how many posts you have, it might take from a few seconds to several minutes for a new PDF to be generated.
<blockquote>
If no PDF is generated you probably don’t have enough server resources. This can’t be fixed, as PDF libraries are very resource-hungry. 
 Ask your hosting to check how many resources you would need to run the plugin and if there is anything you can do, within your hosting limits, to make sure the plugin has enough or appropriate RAM/PHP settings.
</blockquote>
If you don’t use a custom url, hence you don’t add the <code>post_type</code> parameter to the url, the default post type exported will always be WP default <code>post</code>.
<h4>The PDF Template</h4>
Currently, the template and design for the exported pdf, is very basic (and posts are rendered as a table, since floating doesn’t play nicely with the DOMPDF library).
You can copy the plugin’s basic structure from <code>wp-content/plugins/simple-pdf-exporter/assets/pdf_layout.php</code> inside your current theme and edit it. 
Your layout must be echoed in php, eg. <code>echo '<div>the content goes here</div>';</code> or it won’t show up in the PDF.
You can copy the plugin’s basic CSS from <code>wp-content/plugins/simple-pdf-exporter/assets/pdf_export.css</code> inside your current theme and edit it.
Do not edit directly the plugin’s files <code>pdf_layout.php</code> and <code>pdf_export.css</code>, they will be overwritten with the next update.

WordPress PDF Templates
This plugin utilises the DOMPDF Library to provide a simple URL endpoint e.g. http://my-site.com/my-post/pdf/ that generates a downloadable PDF file.
If pretty permalinks are disabled. GET parameters (e.g. ?p=1&pdf) can be used instead.
The PDF output can be customized by copying the index-pdf.php file from the plugin directory to your theme and creating your own custom template for PDF prints.
Stylesheets used on the site are disabled by default, but you can define your own stylesheets within the pdf-template.php file. PDF Templates can be previewed as raw HTML at the /pdf-preview URL endpoint.
