### INSTALLATION
|
|
### ------------
|
|
### To use this script, copy it into your CUPS backends directory, which
|
|
### might be in /usr/lib/cups/backends or /usr/local/lib/cups/backends.
|
|
### Make sure that the script is executable by whatever id cupsd runs
|
|
### with, and then restart CUPS.
|
|
###
|
|
### In order for CUPS to detect your novell printers at boot time you
|
|
### will have to have correctly configured ipx in your kernel, and CUPS
|
|
### must start *after* your network interface card is up.
|
|
###
|
|
### As root, you must be able run "pqlist" and get a list of the
|
|
### printers on your server. The "pqlist" program uses ~root/.nwclient
|
|
### as a mechinism for determining the default novell server to use.
|
|
### This file must be properly configured in order for this backend to
|
|
### detect and use novell printers. Currently this script will only
|
|
### enable printing to print queue's on a single server. If anyone
|
|
### has any ideas on how to support more than one server, please let
|
|
### me know.
|
|
###
|
|
### You should then be able to configure printers in CUPS with the
|
|
### devices you've configured. I have only been able to configure
|
|
### devices with the CUPS web interface.
|
|
###
|
|
### This single script can be used to support multiple devices. However,
|
|
### at this point it can only support access to one print server.
|
|
### This is due to the inability of pqlist to enumerate more than a
|
|
### single server's printers at a time. If anyone has any ideas on how
|
|
### I might make printing to multiple servers function, I'd be glad to
|
|
### hear them.
|
|
###
|
|
### DEPENDANCIES
|
|
### ------------
|
|
### This script is dependant upon builtin commands in bash. It has not
|
|
### been tested against other non-bash shells. I don't expect that
|
|
### it will work with them. You are invited to test other shells.
|
|
### Please let me know if you have any success.
|
|
###
|
|
### This script depends on correctly installed ncpfs software
|
|
### available at: ftp://platan.vc.cvut.cz/pub/linux/ncpfs/
|
|
###
|
|
### This script depends on the following programs being in the PATH
|
|
### pqlist, nprint, basename, cat
|
|
### If these commands are not in /bin, /usr/bin, or /usr/local/bin on
|
|
### your computer, set PATH below to include where they are located.
|
|
|
|
PATH=$PATH:/bin:/usr/bin:/usr/local/bin
|
|
|
|
### Set root's home directory here:
|
|
#HOME=/root
|
|
HOME=~root
|
|
export HOME
|
|
|
|
### Uncomment for crude debugging output
|
|
#DEBUG=true
