cups

puppet-cups module

Important

After git tag 1.4.0_RC1 I have made a non-backwards compatible change to the way ppd_options and options parameters work. If you want to use the old behavior, please use tag 1.4.0_RC1 or 1.3.0

User Guide

Overview

This type provides the ability to manage cups printers and options.

Limitations:

• It currently does not support classes.

Installation

You can install the latest release version from the module forge by executing this command:

puppet module install mosen-cups

You can also clone the source repository into your module path, but be aware that HEAD is sometimes broken.

Examples

Basic

The most basic printer install possible:

printer { "Basic_Printer":
    ensure      => present,
    uri         => "lpd://hostname/printer_a",
    description => "This is the printer description",
    ppd         => "/Library/Printers/PPDs/Printer.ppd", # OR
    model       => "drv:///sample.drv/okidata9.ppd", # Model from `lpinfo -m`
}

• The uri identifies how you will connect to the printer. running lpinfo -v at the command line will give you some valid uri prefixes.
• The description only appears in certain dialogs on linux and friends. On OSX the description is the actual name of the printer.
• The ppd or model parameter specifies the "driver" to use with this printer. You should use model wherever available because most driver software will install straight into the cups model directory. You can get a list of valid models by running lpinfo -m at the command line.

Removing the printer "Basic_Printer" from the previous example:

printer { "Basic_Printer":
    ensure      => absent,
}

Advanced

An example using almost every possible parameter:

printer { "Extended_Printer":
    ensure       => present,
    uri          => "lpd://localhost/printer_a",
    description  => "This is the printer description",
    location     => "Main office",

    # Printer driver/description
    ppd          => "/Library/Printers/PPDs/Printer.ppd", # Full path to vendor PPD
    # OR
    model        => "", # A valid model, you can list these with lpinfo -m, this is usually what you would call a
                        # list of installed drivers.
    # OR
    interface    => "/path/to/system/v/interface/file", # Interface script run for this destination

    shared       => false, # Printer will be shared and published by CUPS
    error_policy => abort_job, # underscored version of error policy
    enabled      => true, # Enabled by default
    options      => {  }, # Hash of options ( name => value ), supplied as -o flag to lpadmin.

    # Vendor/driver options
    page_size    => 'A4',
    input_tray   => 'Tray1',
    color_model  => 'CMYK',  # or 'Gray' usually for grayscale.
    duplex       => '',
    
    # AND Any other custom driver specific option...
    ppd_options  => { 'HPOption_Duplexer' => 'False' }, # Hash of vendor PPD options, set on creation.
}

• To find valid vendor/ppd values for a printer, install it locally using the vendor supplied PPD and run lpoptions -p <dest> -l. You can also read the PPD if that's your thing.
• Note that some options like shared and error_policy are parameters available at creation time only.

Default Printer

To make the basic printer from the previous section the default:

default_printer { "Basic_Printer":
    ensure => present,
    require => Printer['Basic_Printer'],
}

Note that this has almost zero effect on Mac OS X, due to the GUI not really respecting the system wide lpoptions.

Why not add a default property to the printer resource? Because the command line makes it unfeasible to set the default printer to nothing. This makes it impossible for all instances to have default => false. It also means that changing default from true to false sometimes fails and creates a non-idempotent resource. (This could be overcome in future by editing /etc/cups/lpoptions).

Facts

The module provides access to one additional facter fact "printers", which provides a comma separated list of installed printers.

For more information about printer options, models, and uri's, refer to the CUPS documentation.

Bugs

Please submit any issues through Github issues as I don't have a dedicated project page for this module.

Developer Guide

OSX Specifics

Printer Presets

Each printer can have a set of options, normally presented in the print dialog, saved as a named preset. Named presets are stored in property lists at the following location:

~/Library/Preferences/com.apple.print.custompresets._PRINTER_QUEUE_NAME_.plist

Default Printer

If you select "Last Used Printer", it will select the printer in:

~/Library/Preferences/org.cups.PrintingPrefs.plist

As the default printer.

If you want to set the default printer, you probably shouldn't use lpoptions because it only governs the default when submitting jobs under certain circumstances.

Default Paper Size

Again, OSX doesn't respect lpoptions when you set default page size via lpoptions or lpadmin. The file containing the actual default page size is:

~/Library/Preferences/com.apple.print.PrintingPrefs.plist

Under the plist key DefaultPaperID, which has a string that relates to a non-localised paper size. The PrintCore framework seems to have these listed in a binary plist under OSX 10.8. You can dump some localised strings using

/usr/libexec/plistbuddy -c "print" /System/Library/Frameworks/ApplicationServices.framework/Versions/A/Frameworks/PrintCore.framework/Versions/Current/Resources/English.lproj/Localizable.strings

Contributing

You can issue a pull request and send me a message if you like, and I will consider taking the patch upstream :)

Testing

The tests need a lot of improvement, but you can run them with RSpec in the typical way:

Make sure you have:

rake

Install the necessary gems:

gem install rspec

And run the tests from the root of the source code:

rake test

Acceptance Tests

You can execute the beaker tests starting with:

BEAKER_destroy=no bundle exec rspec spec/acceptance

And then re-use the provisioned guests with

BEAKER_destroy=no BEAKER_provision=no bundle exec rspec spec/acceptance

Unset BEAKER_destroy after testing has finished or VM is dirty for the purposes of testing.

You may also use BEAKER_set=centos6, for example, if you do not want to test against the default vagrant box (Currently Ubuntu Precise).
