About XPD Files
XPD files are the way Paris describes the features of the printer. They work either
as standalone files, in the case of HP-PCL printers, or in combination with PPD
(Postscript Printer Description) files, in the case of Adobe Postscript printers.
In general terms XPD files are created and supplied by your distributor. PPD files
are those files supplied by the Printer manufacturer. An XPD for a PostScript
printer simply contains a reference to include a corresponding PPD file in the
XPD.

NOTE:
XPD files contain command options to manage printer resources. These options
enable you to tailor Paris resource management for the particular requirements of
your printer. Refer to the section ‘XPD Resource Management Commands for PCL
and PostScript printers’ on page 38.

editor, however, it is recommended that these should NOT be changed except by
experienced users or under instructions from the distributor.

Windows GDI supported devices
When using GDI to print there are important points to be considered. Firstly, GDI
was not really designed as a production printing method. As a result, it is not
optimized for speed and can struggle to keep up with high speed printers.
Secondly, when using GDI, Paris is passing responsibility for the final output over
to Windows and in turn the manufacturer supplied GDI driver. As a result, the
outcome cannot be guaranteed to print exactly as intended. There could be font
substitutions or incomplete support for some of the Paris features, because the
printer is incapable of imaging the page as originally designed.
