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.

 

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 25.

 

Both XPD and PPD files are text files and can be edited using a standard 

text

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

A full description of the working of XPD and PPD files can be found in ‘

’ in Chapter One of the  PARIS Designer

Reference Manual.

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.
