[GRLUG] Watermarking "Print" Queue

[Adam Tauno Williams]

I've had this stupid task on my to-do list since Febuary of '08;  and 
while I take swings at it occasionally I never arrive at something that 
works.

We have a COBOL application that spools out jobs in PCL [a crude PCL at 
that] on an AIX host.  I have a simple "queue" on that host which instead 
turns the print job into a PDF and mails it to the user (which is very 
popular).

However, users want to do the same thing but have the PDF watermarked with 
"DRAFT".  I've tried various cocktails with enscript, pdftk, etc... but 
never found a working solution.

Anyone have any ideas?
