   * Next, we are going the create the file that provides or "pdf backend" functionality. Defining a new backend is really no more than creating an executable file called in CUPS's backends directory ''/usr/lib/cups/backend'' - this file's name will become the name of the backend. So, for the "pdf" backend we create the file ''/usr/lib/cups/backend/pdf'' and make this a shellscript, the contents of which you can find in the section below - [[#pdf_printer_scripts|PDF Printer Scripts]]. Do not forget to make this new "pdf" script executable: <code>   * Next, we are going the create the file that provides or "pdf backend" functionality.

 </code> This backend will in turn call two other scripts which we shall place in the library directory ''/usr/lib/cups/pdf'' - see next bullet point.\\ The reason the script did not get world-executable permissions, is that the backend program needs to be run as the //root// user - CUPS will only do that if the program is not world-executable. Otherwise, the backend would be run using the unprivileged user account, typically "lp". //The script needs to run as root in order to be able to change ownership of the resulting PDF file to the user who printed it.// </code> This backend will in turn call two other scripts which we shall place in the library directory ''/usr/lib/cups/pdf'' - see next bullet point.\\ The reason the script did not get world-executable permissions, is that the backend program needs to be run as the //root// user - CUPS will only do that if the program is not world-executable.
