For the past couple hours after the Jacob's answer about apsfilter I was
reading about Unix printing.
I am getting more confused about the real meaning of PPD files and
printer drivers.
According to this
http://en.wikipedia.org/wiki/PostScript_Printer_Description
PPD files are post script description files that act as a drivers for
post script printers. This seems clear to me.
According to same page CUPS-PPD are used by CUPS to do post-script
printing on non-postscript printers by directing files through
CUPS-filter. Could somebody explain this things better to me. Every time
I used CUPS the PPD files where enough to enable me printing.
Did I really use some other drivers beside these PPD files or did CUPS
communicate with my printers with some generic driver and just
uses PPD files to do filtering.
In LPD it seems to me that this is more clear as when I run ./SETUP
apsfilter I am really question to select the driver from the Ghostscript
collection.
Thanks to ALL
