PDF printing mit Samba

Erstellt einen virtuellen PDF-Drucker auf dem Samba-Server (Ghostscript, Samba, and Linux).

Aus: PDF Hacks (O'Reilly 2004): HACK #44 Share a PDF Network Printer with Samba

#!/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

# Changelog
# v0.0.6 20030428
#  - Allow options passed as env. variables from print command
#  - Inline and simplify sed (use tr) clean script
#  - Ensure file arrives in PREFIX even if TEMP is used without provided name
#  - Changes from Joshua M. Schmidlkofer <joshua@imr-net.com> 20030425
#    - Debugging, adjustments, and corrections.
#    - Stupid sed sanitizing script. [probably horribly inefficient also]. 
#    - Temp file usage cleanup.
# v0.0.5 20020723
#  - Add support for preset settings
#  - Allow passing of filename provided by client as final filename
#
# 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.
# If you need to modify anything in this script, please provide me with your
# changes, preferably in such a way that the changes are configurable.
