Recreating SMB printer -> PDF -> input program

[Gary Stainburn]

Back in the good old days (F9) I could set up a dummy SMB printer which would 
accept the file and then call a program to deal with it. I used this with 
Apple PS drivers on Windows PC's to create PDF files and email them back to 
the user. These were back in the days before windows PDF printe drivers such 
as CutePDF.

I'm now looking to re-create this on a more modern Fedora box (19, or 21 
depending which box I use).  I've installed CUPS-PDF and configured a virtual 
printer. However, I have two problems:

1) the printer is not storing the file in the directory specified. I set up 
the connection as cups-pdf:/var/spool/cups-pdf/created but it stored the file 
in /root/Desktop/

2) I can't see any method of being able to trigger a program to handle the 
newly created file.

Can anyone suggest what I need to do to sort these problems, or to suggest an 
alternative.
