Comment 9 for bug 600764

Please note that CUPS-PDF is just a CUPS back-end meant to be treated as just any printer with a fixed set of features. Adding any sort of UI to what is essentially a printer driver, rather than a PDF export tool, would not be an easy task.

As for the process of PDF generation in general, please note that the generic GTK2 print dialog already supports configuring a number of print options for its own Save to PDF feature. The same functionalities are also offered by QT for KDE apps. These two toolkit-specific features are the preferred methods for generating PDF documents from an Ubuntu desktop. Meanwhile, CUPS-PDf is instead designed for massively replacing printouts with PDF documents in a corporate setting.
