There are two possibilities how to print the PostScript test page: With a high color photography and without it. The reason is that some PostScript printers may fail printing this high color photography without the job being processed by ghostscript.
Before the test page is printed, the graphics and texts are patched into
it via an external script. The graphics contain the vendor logo and a photo
for testing photographic printing. Texts contain all texts in the test page
(so that the page can be localized). Currently, only
ASCII
and
ISO-8859-1|2|15
encodings are supported.
The queue name, printer vendor and model, PPD file nick name, printer
URI, location description, information and options as adjusted in the
PPD file are patched to the test page too.
