 * Hi, this plugin seems to be promissing but I’m getting a fatal error when creating
   PDFs.
 * `Uncaught Error: Class "Picqer\Barcode\BarcodeGeneratorPNG" not found in /home/
   user/domain.com/wp-content/plugins/pdf-for-woocommerce/backend/templates/barcode_qrcode.
   php:32`
 * Any idea why?

 * I’ve managed to get it work buy uninstalling and re-installing again.
 * Two things only:
 * You should state in plugin description it requires an installation of another
   plugin to work. (which I don’t need).
 * You should also mention free version has a limitation of 15 Pages PDF. Not even
   on your pro-version page, this point is not clear about.

 * Sorry
    1. We will update the description to make this clearer.
    2. We do not impose a limit on the number of PDF pages. The maximum number of pages
       is determined by your server resources. You can increase the `memory_limit` 
       and `max_execution_time` values to generate larger PDFs with more pages.
 * Thank you so much
