| * 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.

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.// |

| * Now that we have the ''pdf'' backend file in place, the next step is to create the two helper scripts that our ''pdf'' script uses. One script does the conversion of PostScript to PDF, while the second does the actual email delivery.\\ Install these two files called "''ps2pdf.cups''" and "''sendpdf''" into the cups library directory which we just created: ''/usr/lib/cups/pdf''. You can find these scripts in the section below called [[#pdf_printer_scripts|PDF Printer Scripts]].
