 * HI,
 * I open the pdf file on my phone, both Android and iPhone. But the pdf content
   can only be seen in google pdf reader or default pdf reader but not in Adobe’s
   pdf reader, anything i missed to do? Is the pdf engine not compatible to latest
   pdf reader?
 * Thanks
 * Raymond

 * Hi raymondleung,
 * DK PDF uses [mPDF](https://mpdf.github.io/) library to generate the PDF, maybe
   you can do a google search to see if there are compatibility issues.
 * Thanks,

 * I experienced the same sometimes.
 * I searched and found this: [https://stackoverflow.com/questions/35276187/php-adobe-reader-cant-open-pdf-files-created-with-mpdf](https://stackoverflow.com/questions/35276187/php-adobe-reader-cant-open-pdf-files-created-with-mpdf)
 * This is also mentioned at [https://mpdf.github.io/what-else-can-i-do/capture-html-output.html](https://mpdf.github.io/what-else-can-i-do/capture-html-output.html)
   and [https://github.com/mpdf/mpdf/issues/115](https://github.com/mpdf/mpdf/issues/115)
 * If this is the case, maybe the fix should be in DK PDF itself. Thoughts?
 * P.S. DK PDF uses mPDF v6.0 from 2014, which is not the latest stable version 
   from [https://github.com/mpdf/mpdf/releases](https://github.com/mpdf/mpdf/releases)
   
   So maybe this is another reason to update the mPDF library and its usage in the
   DK PDF plugin.
