#!/bin/bash
# samba-print-pdf
# This is a script which allows you to set up a virtual printer on samba
# which will take the file (generated by a postscript filter on windows)
# and turn it into a PDF, informing the user of where it is when it
# is done

#
# Arguments:
# $1 = file (usually passed with %s from samba)
# $2 = unix prefix to where to place the file (~%u should work)
# $3 = windows prefix to the same location (//%L/%u should work)
# $4 = user/computer to send a notification to (%u or %m)
# $5 = IP address of client (%I)
# $6 = Name of destination file without extension (%J)
# $7 = PDF setting (prepress,print,screen etc)
#
# If you want to customise any of the following configuration defaults, 
# you can place them in the file /etc/samba/print-pdf.conf.
