Introduction

This page covers only how to install a Netware Printer Queue in Ubuntu.

What is Needed

perl - Larry Wall's Practical Extraction and Report Language, needed for ncp script. ipx - utilities to configure the kernel ipx interface. ncpfs - a set of utilities to use resources from NetWare servers, in particular nprint to print to a netware printer queue. kdeprint - print system for KDE, this is a very nice tool.

NCP script

Create the script /usr/lib/cups/backend/ncp

#! /usr/bin/perl -w
#
# NCP backend for CUPS

Restart CUPS After changing this file, restart CUPS by running ...

sudo /etc/init.d/cupsys restart

or use the Services tool under Gnome menu System -> Administration.

Add a Netware Printer with Gnome menu System and kdeprint

1. Add a printer definition, using kdeprint (Gnome menu System -> Preferences -> Printers). Select Other printer type. In the URl: type

ncp://COMPANY_FS/PRINTER_Q

If at this point you don't see 'Netware Printer via ncp' then refer to 'NCP Script' above. Select the relevent printer etc. and you should have a working Netware Printer.

Add a Netware Printer with Cups Web Interface

This needs an Administrator account. Please refer to NetworkPrintingWithUbuntu -> Ubuntu Client Machine for more info.

# /etc/cups/cupsd.conf
# Simple CUPS configuration file for a pure client machine:
# which has:
# - printers of its own, (and any local printers will be shared?)
# - no need for security within the machine, ie a personal workstation
# - a network connection to a local network, where it will find CUPS-controlled printer servers

# Log general information in error_log - change "info" to "debug" for
# troubleshooting...
LogLevel warning

# Administrator user group...
SystemGroup lpadmin

# Only listen for connections from the local machine.
# These settings are configured in /etc/cups/cups.d/ports.conf so that
# changing them does not require to change this file.
# Listen localhost:631
