Editing PostScript Printer Description (section)

== Windows ==
[[Microsoft Windows]] also uses PPD files but converts these to a binary .BPD file format before using them. These, both PPD and BPD, are normally stored in <code>%WINDIR%\system32\spool\drivers\w32x86\3</code> on an x86 system, or <code>%WINDIR%\System32\spool\drivers\x64\3</code> on a 64 bit system.

Updating a PPD file requires four steps:
# stop the spooling service;
# edit the existing PPD file in place or replace it by an updated version;
# remove the old BPD file;
# restart the spooling service.
This will automatically generate a new BPD from the updated PPD.
