Fix cups-pdf not printing PDFs with restrictions

Fix problem when cups-pdf (actually Ghostscript) refuses to print PDF files with restrictions

Specifically, even if the file has no printing restrictions, like many government forms do (my specific itch), Ghostscript refuses to print the file and generates a blank pdf.

Steps to fix

  1. Put contents of unblockprint.sh in an executable file named /usr/lib/cups/filter/unblockprint. Make sure that the permissions of this file matches others in the same directory.
  2. Put local.convs in /etc/cups
