# ipp-usb.conf: example configuration file

# Networking parameters
[network]
  # TCP ports for HTTP will be automatically allocated in the following range
  http-min-port = 60000
  http-max-port = 65535

  # Enable or disable DNS-SD advertisement
  dns-sd = enable      # enable | disable

  # Network interface to use. Set to `all` if you want to expose you
  # printer to the local network. This way you can share your printer
  # with other computers in the network, as well as with iOS and Android
  # devices.
  interface = loopback # all | loopback

  # Enable or disable IPv6
  ipv6 = enable        # enable | disable

# Local user authentication by UID/GID
[auth uid]
  # Syntax:
  #     operations = users
  #
  # Operations are comma-separated list of following operations:
  #     all    - all operations
  #     config - configuration web-console
  #     fax    - faxing
  #     print  - printing
  #     scan   - scanning
  #
  # Users have the following suntax:
  #     user   - user name
  #     @group - all users that belongs to the group
  #
  # Users and groups may be specified either by names or by
  # numbers. "*" means any
  #
  # Note, if user/group is not known in the context of request
  # (for example, in the case of non-local network connection),
  # "*" is used for matching, which will only match wildcard
  # rules.
  #
  # User/group names are resolved at the moment of request
  # processing (and cached for a couple of seconds), so running
  # daemon will see changes to the /etc/passwd and /etc/group
  #
  # Examples:
  #     fax, print = lp, @lp   # Allow CUPS to do its work
  #     scan       = *         # Allow any user to scan
  #     config     = @wheel    # Only wheel group members can do that
  all = *

# Logging configuration
[logging]
  # device-log  - per-device log levels
  # main-log    - main log levels
  # console-log - console log levels
  #
  # parameter contains a comma-separated list of
  # the following keywords:
  #   error     - error messages
  #   info      - informative messages
  #   debug     - debug messages
  #   trace-ipp, trace-escl, trace-http - very detailed per-protocol traces
  #   trace-usb - hex dump of all USB traffic
  #   all       - all logs
  #   trace-all - alias to all
  #
  # Note, trace-* implies debug, debug implies info, info implies error
  device-log    = all
  main-log      = debug
  console-log   = debug

  # Log rotation parameters:
  #   max-file-size    - max log file before rotation. Use suffix M
  #                      for megabytes or K for kilobytes
  #   max-backup-files - how many backup files to preserve during rotation
  #
  max-file-size    = 256K
  max-backup-files = 5

  # Enable or disable ANSI colors on console
  console-color = enable # enable | disable

  # ipp-usb queries IPP printer attributes at the initialization time
  # for its own purposes and writes received attributes to the log.
  # By default, only necessary attributes are requested from device.
  #
  # If this parameter is set to true, all printer attributes will
  # be requested. Normally, it only affects the logging. However,
  # some enterprise-level HP printers returns such huge amount of
  # data and do it so slowly, so it can cause initialization timeout.
  # This is why this feature is not enabled by default
  get-all-printer-attrs = false # false | true
