I am new to cups (1.1.10). I've installed it and configured it via the web
interface. I have successfully configured an HP Deskjet printer to work via
the local parallel port (/dev/lp0). I am able to control the printer fine
(start, stop, etc). I have been able to successfully print a test page from
the web interface as well as from KDE. But, I cannot print anything else,
from anywhere else. The jobs show up as completed in the job queue ("Show
completed jobs"), but nothing prints other than test pages. I am the root
user on a slackware 8.0 box (the only user), using an HP Deskjet 600C on a
local parallel port (/dev/lp0). I print mainly Postscript (which worked fine
using BSD LPD). Here is a cut from my error_log - the last three jobs.
- Job 13 is a KDE test page. Job 14 and 15 are ps files, and are not
printing. Also, there is the whole page_log file after this. Note: The
only thing I did out of the ordinary was to disable the authentification
stuff so that I could get into the admin part of the web access. So, I will
also include the cupsd.conf after the page_log. The client.conf file is
totally commented out (I haven't changed anything there)

######## Network Options
########
#
# Ports/addresses that we listen to. The default port 631 is reserved

# Listen hostname:631
# Listen 1.2.3.4
# Listen 1.2.3.4:631
#
# NOTE: Unfortunately, most web browsers don't support TLS or HTTP Upgrades
# for encryption. If you want to support web-based encryption you'll

#
#Port 80
#Port 443
Port 631
#
# HostNameLookups: whether or not to do lookups on IP addresses to get a
# fully-qualified hostname. This defaults to Off for performance reasons...

######## Browsing Options
########
#
# Browsing: whether or not to broadcast and/or listen for CUPS printer
# information on the network. Enabled by default.
#
#Browsing On
#
# BrowseProtocols: which protocols to use for browsing. Can be
# any of the following separated by whitespace and/or commas:
#
# all - Use all supported protocols.
# cups - Use the CUPS browse protocol.
# slp - Use the SLPv2 protocol.
#
# The default is "cups".
#
# NOTE: If you choose to use SLPv2, it is *strongly* recommended that
# you have at least one SLP Directory Agent (DA) on your
# network. Otherwise, browse updates can take several seconds,
# during which the scheduler will not response to client
# requests.
#
#BrowseProtocols cups
#
# BrowseAddress: specifies a broadcast address to be used. By
# default browsing information is not sent!
#
# Note: HP-UX does not properly handle broadcast unless you have a
# Class A, B, C, or D netmask (i.e. no CIDR support).
#
# Note: Using the "global" broadcast address (255.255.255.255) will
# activate a Linux demand-dial link with the default configuration.
# If you have a LAN as well as the dial-up link, use the LAN's
# broadcast address.
#
#BrowseAddress x.y.z.255
#BrowseAddress x.y.255.255
#BrowseAddress x.255.255.255
#BrowseAddress 255.255.255.255
#
# BrowseShortNames: whether or not to use "short" names for remote printers
# when possible (e.g. "printer" instead of "printer@host".) Enabled by
# default.
#
#BrowseShortNames Yes
#
# BrowseAllow: specifies an address mask to allow for incoming browser
# packets. The default is to allow packets from all addresses.
#
# BrowseDeny: specifies an address mask to deny for incoming browser
# packets. The default is to deny packets from no addresses.
#
# Both "BrowseAllow" and "BrowseDeny" accept the following notations for
# addresses:
#
# All
# None
# *.domain.com
# .domain.com
# host.domain.com
# nnn.*
# nnn.nnn.*
# nnn.nnn.nnn.*
# nnn.nnn.nnn.nnn
# nnn.nnn.nnn.nnn/mm
# nnn.nnn.nnn.nnn/mmm.mmm.mmm.mmm
#
# The hostname/domainname restrictions only work if you have turned hostname
# lookups on!
#
#BrowseAllow address
#BrowseDeny address
#
# BrowseInterval: the time between browsing updates in seconds. Default
# is 30 seconds.
#
# Note that browsing information is sent whenever a printer's state changes
# as well, so this represents the maximum time between updates.
#
# Set this to 0 to disable outgoing broadcasts so your local printers are
# not advertised but you can still see printers on other hosts.
#
#BrowseInterval 30
#
# BrowseOrder: specifies the order of BrowseAllow/BrowseDeny comparisons.
#
#BrowseOrder allow,deny
#BrowseOrder deny,allow
#
# BrowsePoll: poll the named server(s) for printers
#
#BrowsePoll address:port
#
# BrowsePort: the port used for UDP broadcasts. By default this is
# the IPP port; if you change this you need to do it on all servers.
# Only one BrowsePort is recognized.
#
#BrowsePort 631
#
# BrowseRelay: relay browser packets from one address/network to another.
#
#BrowseRelay source-address destination-address
#
# BrowseTimeout: the timeout for network printers - if we don't
# get an update within this time the printer will be removed
# from the printer list. This number definitely should not be
# less the BrowseInterval value for obvious reasons. Defaults
# to 300 seconds.
#
#BrowseTimeout 300
#
# ImplicitClasses: whether or not to use implicit classes.
#
# Printer classes can be specified explicitly in the classes.conf
# file, implicitly based upon the printers available on the LAN, or
# both.
#
# When ImplicitClasses is On, printers on the LAN with the same name
# (e.g. Acme-LaserPrint-1000) will be put into a class with the same
# name. This allows you to setup multiple redundant queues on a LAN
# without a lot of administrative difficulties. If a user sends a
# job to Acme-LaserPrint-1000, the job will go to the first available
# queue.
#
# Enabled by default.
#
#ImplicitClasses On
#
# ImplicitAnyClasses: whether or not to create "AnyPrinter" implicit
# classes.
#
# When ImplicitAnyClasses is On and a local queue of the same name
# exists, e.g. "printer", "printer@server1", "printer@server1", then
# an implicit class called "Anyprinter" is created instead.
#
# When ImplicitAnyClasses is Off, implicit classes are not created
# when there is a local queue of the same name.
#
# Disabled by default.
#
#ImplicitAnyCLasses Off
#
# HideImplicitMembers: whether or not to show the members of an
# implicit class.
#
# When HideImplicitMembers is On, any remote printers that are
# part of an implicit class are hidden from the user, who will
# then only see a single queue even though many queues will be
# supporting the implicit class.
#
# Enabled by default.
#
#HideImplicitMembers On
########
######## Security Options
########
#
# SystemGroup: the group name for "System" (printer administration)
# access. The default varies depending on the operating system, but
# will be "sys", "system", or "root" (checked for in that order.)
#
#SystemGroup sys
#
# Access permissions for each directory served by the scheduler.
# Locations are relative to DocumentRoot...
#
# AuthType: the authorization to use:
#
# None - Perform no authentication
# Basic - Perform authentication using the HTTP Basic method.
# Digest - Perform authentication using the HTTP Digest method.
#
# (Note: local certificate authentication can be substituted by
# the client for Basic or Digest when connecting to the
# localhost interface)
#
# AuthClass: the authorization class; currently only "Anonymous", "User",
# "System" (valid user belonging to group SystemGroup), and "Group"
# (valid user belonging to the specified group) are supported.
#
# AuthGroupName: the group name for "Group" authorization.
#
# Order: the order of Allow/Deny processing.
#
# Allow: allows access from the specified hostname, domain, IP address, or
# network.
#
# Deny: denies access from the specified hostname, domain, IP address, or
# network.
#
# Both "Allow" and "Deny" accept the following notations for addresses:
#
# All
# None
# *.domain.com
# .domain.com
# host.domain.com
# nnn.*
# nnn.nnn.*
# nnn.nnn.nnn.*
# nnn.nnn.nnn.nnn
# nnn.nnn.nnn.nnn/mm
# nnn.nnn.nnn.nnn/mmm.mmm.mmm.mmm
#
# The host and domain address require that you enable hostname lookups
# with "HostNameLookups On" above.
#
# Encryption: whether or not to use encryption; this depends on having
# the OpenSSL library linked into the CUPS library and scheduler.
#
# Possible values:
#
# Always - Always use encryption (SSL)
# Never - Never use encryption
# Required - Use TLS encryption upgrade
# IfRequested - Use encryption if the server requests it
#
# The default value is "IfRequested".
