samba - Feb 2002 - Printer pooling with samba / CUPS pool 2 printers with one logical "queue"

Joel, thanks for posting. I will have to work on
figuring that portion out. The crappy thing is, if I
get a CUPS documentation book, it'll tell me how to
make stuff work in CUPS. the problem is, getting Samba
to interact with that part of CUPS. And there seems to
be no documentation on how to print pool with
CUPS/Samba

Install both printers on CUPS (as root):

#  lpadmin -p hp4100_1 -E -v socket://192.168.5.13:9100 -P /path/to/PPD-file
#  lpadmin -p hp4100_2 -E -v socket://192.168.5.14:9100 -P /path/to/PPD-file

Create a CUPS class for the 2 printers:

#  lpadmin -p hp4100_1 -c hp_class
#  lpadmin -p hp4100_2 -c hp_class

Put a share for this class manually into smb.conf:

#  [hp_class]
#     comment = CUPS-"class" of printers
#     browseable = yes
#     printable = yes
#     public = yes
#     read only = yes
#     create mode = 0700
#     directory = /tmp

Restart smbd.

You should now be able to "see" the class now like a normal printer in
the
network neighbourhood. You can't directly download a driver for it from the
CUPS server (as with normal printers). You need to install a driver through
one of the other means. If you print to this printer class, the jobs get
alternately printed by one of the members (round-robin) as long as they are
both alive. If one is down, the other does the whole lot. Works also with
bigger classes.

Good luck!
