Cannot get dompdf to work I have extracted the dompdf libraries folder to /sites/all/libraries

Re: 2. Edit dompdf_config.inc.php to fit your installation.

What exact changes do I need to make to this file???

Also, I am getting this warning in the drupal admin:


  Warning: in_array() expects parameter 2 to be array, integer given in print_pdf_settings() (line 22 of /home/mysite/public_html/sites/all/modules/print/print_pdf/print_pdf.admin.inc).
Print module works best when you copy the library dompdf (or tcpdf) to the module folder directly. In this was you don't need to edit the file, and the print module will detect the library automatically.


Extract the dompdf directory into sites/all/modules/print so that you have dompdf_config.inc at sites/all/modules/print/dompdf/dompdf_config.inc.
Ensure that you have write access to PUBLIC/print_pdf/dompdf/fonts directory.
Your print module should now show the detection of the library at admin/config/user-interface/print/pdf.

You should now be able to export the nodes to PDF :)
