CUPS-PDF provides a PDF Writer backend to CUPS. This can be used as a virtual printer in a paperless network or to perform testing on CUPS.

Documents are written to a configurable directory (by default to ~/PDF) or can be further manipulated by a post-processing command.

Note that AppArmor prevents outputting PDF documents to non-default directories so must also be edited, whenever the above default get changed in .

In cases where the system mounts home directories from paths other than , edit instead.

Desktop users might find it simpler to use the Print To File feature provided by GTK+ and QT or the LibreOffice's Export to PDF feature.
