# Blatently lifted from some folks who blatently lifted it from

# This script supports sending a print job to an SMB (Samba/Microsoft)
# printer using the 'smbclient' from the Samba distribution.
#
# Variation 1: LPRng + smbclient -A auth
#  smb:lp=|/.../smbprint
#   :sd=/var/spool/lpd/%P
#   :xfer_options=share=//host/share authfile=auth
#    - user name and password in /var/spool/lpd/smb/auth file 
#    - requires version of smbclient that uses -A authfile
# Variation 2: LPRng + smbclient -U username password
#  smb:lp=|/.../smbprint
#   :sd=/var/spool/lpd/%P
#   :xfer_options=share=//host/share authfile=auth
#    - user name and password in /var/spool/lpd/smb/auth file 
#    - requires version of smbclient that uses -A authfile
# Variation 3: LPRng + used as filter
#  smb:lp=/dev/null
#   :if=/.../smbprint
#   :sd=/var/spool/lpd/%P
#   :xfer_options=share=//host/share authfile=auth
#    - user name and password in /var/spool/lpd/smb/auth file 
# Variation 4: pass options in $spooldir/general.cfg file
#  smb:lp=/dev/null OR lp=|/.../smbprint OR :if=/.../smbprint
#    - options in /var/spool/lpd/smb/general.cfg file 
#
#  The general.cfg file is used to set shell variables
#
#   share=//host/share   - share (required)
#   hostip=              - host ip address (optional)
#   workgroup=           - workgroup (required)
#   authfile=auth        - authorization file (optional)
#   translate=           - do translation (optional and DANGEROUS)
#
# The authentication file (authfile) holds the username and
# password value.  You can put these in the general.cfg file
# as well.  WARNING: smbclient requires the authentication file
# to have the format:
#     username=name
#     password=xxxx
# There are NO quotes allowed around the name and/or password
# files so the password value xxxx must not contain shell
# quote or metacharacters.
