DOCBOOK: Disalloingw printing of pdf-files made with docbook

I'm writing a rather long (200 pages with lots of colorful screendumps)
userdocumentation for our linuxsystem at my school, and I make pdf-files
with the command 'docbook2pdf', and I wonder if anyone knows if it's
possible to disalloingw printing of this file. Either via docbook, or any
other command on a linuxmachine.
