[cups.general] PDF printing

[Per Qvindesland]

Hello List.

I am looking at setting up a print server that I would like to save all
prints to a folder as a pdf and then a second program
http://www.qoppa.com/pas/pasindex.html will convert the program to a
jpeg file (to save space) and then do the actual printout a normal
printer.

My question is if there is any pdf printer that will do just that or if
I am trying to achieve something really off the scale stupid here. 

Kind regards
Per Qvindesland
