Approach:
----------------------------------------------------------
The 'print' module supports 4 different PDF generation libraries(dompdf, mPDF, TCPDF, wkhtmltopdf). Now it need to know which library you are using. Also you said you are using tinymce. Usually, in drupal 7 tinymce installed via Wysiwyg . Then tinymce library is uploaded.
So according to the issue you specified, the problem lies in PDF generation process.
It can be solved within 3 days.
Waiting to hear from you
