Now after restarting CUPS you will be able to choose "Virtual Printer (PDF Printer)" when setting up a new printer in CUPS.

To set up a queue for other UNIX clients you should select Postscript as vendor and the Color Printer as model for your new printer; queues that get their input from samba or netatalk (i.e. Windows, OS/2 or MacOS) can be set up as raw queues. On the Windows, OS/2 or MacOS system choose a color postscript driver for that network printer (the drivers for Minolta Page Works or HP DesignJet printers do a good job).

Hint: If you want to create grayscale PDFs you just have to choose a grayscale printer driver, i.e. the postscript.ppd that comes with CUPS on the Linux side or a b/w laser printer (e.g. a HP LaserJet) on the Windows side. On the Linux side be aware that the postscript.ppd will not re-process data that is already supplied in Postscript format, i.e. a color Postscript will keep it's colors.

Once you print to the new device the output directory selected in cups-pdf.h (defaults to /var/spool/cups-pdf) will be created and all converted PDF files will be placed in subdirectories named after the owner of the print job. In case the owner cannot be identified (i.e. does not exist on the server) the output is placed in the subdirectory for anonymous operation (if not disabled in cups-pdf.h - defaults to ANONYMOUS/). Furthermore if logging is enabled the logfile will be placed by default in /var/log/cups.

The file "PostscriptColor.ppd.gz" is a modified version of the "Postscript.ppd.gz" that comes with CUPS 1.1.15 that is able to handle color output.
