I’m having the same issue (still). Any updates on fixing the bug? The shortcodes I use typically involve [ccie] from CodeColorer, and $latex from WordPress itself…

Here’s an example where it all comes together (or not as of yet):

So, I modified the plugin to simply hide all errors and warnings by inserting error_reporting(0); at the beginning of the pdf-print.php file. I suppose error_reporting(E_ERROR); would also work, because that still enables error messages, but hides all warnings.

PS: this is merely a quick fix and not a solution to the bug in the long term…

Hi, I have the same issue as it seems:

I am using Version 2.0.2 and have PHP 7.2 (hosted on 1&1) when I got this error. I had to downgrade to PHP 7.0 to no longer get the messages (and a properly formatted PDF). The warnings I see in the generated PDF file when using PHP 7.2 are:

<br />

We are also inclined to buy a license for this plugin for our website, but if this bug cannot be fixed by 12/2018 (which is when the 1&1 support for PHP 7.0 expires) then I’d hesitate to do so.

PS: The print function seems to work fine in PHP 7.2 (no visible warnings at least). So I’d guess the bug is somewhere in the PDF-related code.
