CUPS Cloud Print

Found CUPS Cloud Print useful?

Introduction

CUPS Cloud Print is a Google Cloud Print driver for UNIX-like operating systems ( Linux, Mac OS X , BSDs etc ). It allows any application which prints via CUPS to print to Google Cloud Print directly.

Why?

Assuming you have Print-Cloud-Ready printer, Google Cloud Print allows you to print to your printer without installing any printer specific drivers – aside from the obvious advantages of not having to install drivers for every printer you come into contact with, it allows you to use a proprietary printer on platforms you would not normally easily be able to use ( for example, printing from an ARM-based Raspberry Pi to a printer where the manufacturer only provides x86 proprietary drivers ).

Also, because Google Docs ( Google Drive ) presents itself as a printer to Cloud Print, it also means you can ‘print’ directly to Google Docs using CUPS Cloud Print ( some users have leveraged this functionality to scan to Google Docs ).

I generally use Gentoo , CentOS and Ubuntu, but I’ve tried to create packages to suite 99% of Linux distributions. All packages are set as noarch ( or the distro’s equivalent ), so should work on any CPU architecture ( x86, x86_64, ARM, MIPS etc ).

If there is a (Free) OS which you require packages for, please comment below and I’ll investigate creating packages for it.

Please select your Operating System for installation instructions:

Ubuntu 10.04+ , Kubuntu 10.04+ , Xubuntu 10.04+ , Mint 10+ etc - PPA Based Installation

Run in a terminal:

sudo add-apt-repository ppa:simon-cadman/cups-cloud-print
sudo apt-get update
sudo apt-get install cupscloudprint
sudo /usr/share/cloudprint-cups/setupcloudprint.py

Follow the instructions about authorising CUPS Cloud Print to use your Google Account for printing, and you're done.

Debian Squeeze+ , MEPIS 11+ etc - .deb file based installation

If your OS supports PPA repositories, it is preferable to install using PPAs, you will then automatically receive updates when new versions are released.

If you need to install using a deb file, run in a terminal ( as root, or using sudo ):

wget https://niftyrepo.niftiestsoftware.com/cups-cloud-print/packages/cupscloudprint_20140702-1_all.deb

Run in a terminal ( as root, or using sudo ):

rpm --import https://niftyrepo.niftiestsoftware.com/rpm/RPM-GPG-KEY-niftiestsoftware
rpm -i https://niftyrepo.niftiestsoftware.com/cups-cloud-print/packages/cupscloudprint-20140702-1.noarch.rpm 
/usr/share/cloudprint-cups/setupcloudprint.py

Follow the instructions about authorising CUPS Cloud Print to use your Google Account for printing, and you're done.

Gentoo, Sabayon, Funtoo etc - Portage Ebuild

The preferred way to install CUPS Cloud Print on Gentoo is using my layman repository - simply run in a terminal (as root with layman installed):

layman -o https://raw.github.com/simoncadman/niftyrepo-layman/master/repositories.xml -f -a niftyrepo
emerge -va cupscloudprint
/usr/share/cloudprint-cups/setupcloudprint.py

Then follow the instructions about authorising CUPS Cloud Print to use your Google Account for printing.

You can alternatively download the latest ebuild manually to a local overlay and emerge as normal.

Arch, Chakra etc - Arch Pacman

Add to /etc/pacman.conf:

[niftyrepo]
Server = https://niftyrepo.niftiestsoftware.com/arch
SigLevel = Required TrustAll

Then run in a terminal ( as root, or using sudo ), answering 'Y' when asked to the import PGP key ( 2048R/C5541D9D ):

pacman -Syu cupscloudprint
/usr/share/cloudprint-cups/setupcloudprint.py

Follow the instructions about authorising CUPS Cloud Print to use your Google Account for printing, and you’re done.

You can alternatively download the latest arch PKG file and install as normal.

Other (Source install) - Source Install

Run in a terminal ( as root, or using sudo ):

git clone git://github.com/simoncadman/CUPS-Cloud-Print.git
cd CUPS-Cloud-Print/
git checkout tags/20140702
./configure
make install
/usr/local/share/cloudprint-cups/setupcloudprint.py

Follow the instructions about authorising CUPS Cloud Print to use your Google Account for printing, and you're done.

When upgrading, you should always run:

/usr/local/share/cloudprint-cups/upgrade.py

Instructions for running source install
Run in a terminal ( as root, or using sudo ):
git clone git://github.com/simoncadman/CUPS-Cloud-Print.git
cd CUPS-Cloud-Print/
git checkout tags/20140702
./configure
gmake install
/usr/local/share/cloudprint-cups/setupcloudprint.py
Follow the instructions about authorising CUPS Cloud Print to use your Google Account for printing, and you're done. When upgrading, you should always run:
/usr/local/share/cloudprint-cups/upgrade.py

After installing CUPS Cloud Print ( see Installation ), you should first run the setup script, as root ( if you install from source the path will be /usr/local/share/cloudprint-cups ):

/usr/share/cloudprint-cups/setupcloudprint.py

This will create a CUPS printer for each Google Cloud Print printer on your account, and ( if it is the first time you have installed CUPS Cloud Print ) prompt you to allow CUPS Cloud Print to print using your account.

If you notice any bugs or would like to request a feature, please create an issue on the project’s Github issues page .

Which platforms can CUPS Cloud Print run on?

The supported operating systems are listed on the nstallation instructions section. It should work on any platform which those operating systems run on ( Raspberry Pi, embedded hardware such as routers, etc ).

I also generally prefer to only support Free operating systems for my software.

How do I remove google accounts from CUPS Cloud Print?

The deleteaccount.py script will remove accounts from CUPS Cloud Print:

sudo /usr/share/cloudprint-cups/deleteaccount.py

I've shared a CUPS Cloud Print printer over Samba for a Windows client, which printer driver should I use?

The "Samsung CLP-660 Series PS" printer driver works under Windows 7, but it may not work 100%, as it is unsupported. I believe basic printing does work though.

Google has added new options for my printer, but CUPS is not showing them as options, how to I force CUPS Cloud Print to refresh the printer capabilities?

Running the upgrade script refreshes the available printer options:

sudo /usr/share/cloudprint-cups/upgrade.py

  1. Hi Simon,
    I just tried to follow your instructions for Arch, Chakra, etc. (I am using Manjaro).
    After adding the repo, I get this:
    $ pacman -Syu cupscloudprint
    (…)
    :: Importo la chiave PGP 2048R/C5541D9D, “Simon Cadman “, creata: 2012-03-14? [S/n]
    errore: niftyrepo: signature from “Simon Cadman ” is unknown trust

    Can you help?

  2. Hi Cris,

    Sorry, the instructions were slightly wrong, I’ve updated them now, in /etc/pacman.conf you also need to add ‘TrustAll’ to the SigLevel line in the repository.

    Hope this helps

    Thanks

    Simon

  3. Hi João,

    That fix refers to an issue with the prefix functionality, unfortunately you’ll need to delete and re-add any printer you rename.

    Hope this helps

    Simon

  4. I realize you mention a specific unresolved dependency being ok to ignore, but the problem is that some systems (like YAST in OpenSuse) trigger exceptions and pop ups every time it encounters these while evaluating the system.


    nothing provides system-config-printer-libs needed by cupscloudprint-20140112-1.noarch

    That means you have to deal with this manually every time you go into yast/zypper to do any package management.

    Surely something can be done about this in the RPM?

  5. Hello, I need some help.

    For a few months now, when I print through CUPS Cloud Print, from my Ubuntu 12.04 LTS it gets stuck somewhere on the way to the printer. On the Google’s Print Job page, shows that some kind of an error took place.

    How do I fix it?

    Greetings, D

  6. Under fedora 20 the path to the setup py is /usr/share/cloudprint-cups/setupcloudprint.py

    otherwise nice work. Thanks!

  7. Hi,

    This should be fixed next time you update your system, I’ve added a dummy ‘system-config-printer-libs’ package with a 0 version number (to prevent it being accidentally installed on other RPM based distros), which solves this error.

    Unfortunately ( unlike some other package systems ) RPMs don’t support optional dependencies, or choosing one of multiple dependencies, so this is the only way I’ve found to solve this, other than creating a separate RPM repo exclusively for openSUSE.

    Hope this helps

    Simon

  8. Hi Dobri,

    I had this issue once before with my HP printer, and it was because the firmware needed upgrading on the printer ( it seemed that I also needed to re-initialize it back with HP e-printcenter afterwards ).

    Hope this helps

    Simon

  9. Brilliant!!!! There is no Ubuntu driver that will work with my MG7120. I banged my head against the wall for a while, but this totally solved the problem. Bravo!!!!

  10. Hi, thanks for writing the app… I’m trying to install it on a RaspberryPi, but when I enter the following;
    sudo add-apt-repository ppa:simon-cadman/cups-cloud-print

    I get the error message ‘Error: could not find a distribution template’

    Can it run on Raspbian?

    Thanks for your help

  11. Hi, I’ve been using your software successfully on Ubuntu, but I would also like to install it on my Rasberry Pi running Raspbian…. Does it work on Raspbian too?
    Thanks!

  12. Hi Richard,

    Currently the Ubuntu PPA only works with Ubuntu, but the “Debian Squeeze+ , MEPIS 11+ etc – .deb file based installation” instructions should work with Raspbian. I’ll look at adding a Debian PPA-type repository in the future.

    Thanks

    Simon

  13. Hi!

    I am on Version 32.0.1700.102 Built on Ubuntu 13.10, running on LinuxMint 16 (32.0.1700.102-0ubuntu0.13.10.1~20140128.970.1)

    The install went absolutely without any problem and I can see my “Cloud Print” printers in my printing dialog box.

    But when I launch a print job, pop-us display ok messages, including the “printed” message. The Google Cloud Print log shows that my document has been printed, too, but… nothing has been printed.

    The next minute, and without changing anything, I launch the “Try it now!” test page through the Google Cloud Print support pages, and that page (flying documents, clouds, man holding a smwartphone in left hand, etc.) gets successfully printed by the same printer as before.

    Can anyone please help me out?

    Thanks in advance!

  14. Hi Simon,

    Thanks for the response. I can print on it, from other devices, so it is not a Google problem. Only when printing from the CUPS gives this “Error” message, that shows in the Google Cloud Print Control panel (the Print Jobs page).

    :) D

  15. Hi Simon,

    it seems that You didn’t got my comment on Your project. I’m playing around some time with cups pdf-creation. Because of that I inspected Your backend to learn and to improve my own approach. Generally a backend should not perform any filtering or manipulation. Filtering is specified in the ppd. If there are no *cupsfilter lines in the ppd, cups assumes the printer to accept ps and the backend always will receive ps files. This is the case in Your approach. Your backend transforms these ps files with ps2pdf. But now also on Linux (as in OS X) pdf is the standard print job format. Thus in Your approach pdf is transformed to ps and then back to pdf. I suggest to add lines like the following to the ppd:

    *% added cups filter directives
    *% the printer accepts pdf und ps, which is filtered to pdf
    *cupsFilter: “application/vnd.cups-pdf 0 -”
    *cupsFilter: “application/vnd.cups-postscript 100 pstopdffilter”

    Then the backend is fed with pdf and no more transformation is needed. This approach is used in PDFwriter for OS X, which therefore is much better than cups-pdf. Maybe the fault is google’s one, if they provide the ppd (I’m not familiar with GCP). You can also perform page orientation etc. by the pdftopdf filter of cups, which should be easier than other ways.

    Best wishes

    Andreas

  16. Hi Dobri,

    Interesting, can you get the error from the list of jobs ( clicking the ‘details’ button on the print job )?

    It’s also worth checking you are running the latest version of CUPS Cloud Print ( currently 20140210 ).

    Thanks

    Simon

  17. Hi Andreas,

    I don’t seem to have got your other comment, it may have been caught in the spam filter for some reason ( I get about 100 spam messages a day so don’t always have time to check them all completely without deleting them ).

    Those lines are already present the generated ppds ( see here , lines 113 and 114 ), albeit in the reverse order ( the second to last parameter is the ‘cost’, and lowest is used by default, so the pdf format should be used by default on versions of CUPS that support PDF printing ). I believe this was added in release 20130718.

    The ps2pdf part of the backend script is still present for older versions of CUPS that supply the postscript files by default ( I believe the version of CUPS in CentOS 6 still sends postscript files ).

    Thanks

    Simon

  18. Does what it says on the tin perfectly and without fuss.

    Made one of the aspects of switching to Linux very easy.

  19. Hi Simon,

    This is what I get:

    To be sure, that I have the latest version (because I don’t know how to check it :P ), before the printing I removed and re-installed my account and the CUPS-Cloud printer.

    Thank’s for the support and sorry, if I am a bother. :)

  20. Hi Dobri,

    Can you try the latest release ( version 20140307 ) please? I’m still not sure what the problem you are having is, but I did make a change that fixes a possibly similar issue that was reported with Adobe reader.

    You can check the version you are running using your package manager ( on Ubuntu the command would be: apt-cache show cupscloudprint ).

    Thanks

  21. Hi Axel,

    Precise Puppy seems to be based on Ubuntu, so the Ubuntu ( PPA based ) install instructions should work.

    Hope this helps

    Simon

  22. Hi Simon, I test installation on Puppy
    Ubuntu ( PPA based ) install instructions do not work in my Puppy.
    But, deb file based installation works the first step.
    The last message befor stop is:

    dpkg:package cupscloudprint depends on python2.7 python2.6, which cannot be satisfied

    Can you help my please?

  23. It´s possible to rename the printer in cups to a different name defined by the CUPS Cloud Print?

  24. Hi Axel,

    You should be able to install the package using dpkg with the –ignore-depends parameter, you may just need to install these dependencies through Puppy manually:

    python2.7 or python2.6, cups, python-cups, python-httplib2, imagemagick, ghostscript

    Hope this helps

  25. Thanx
    This procedure & command works fine at my Ubuntu 14.01

    I can print on Cloud Printer.

  26. First of all: Nice project, keep it up!

    second – not actually printing results, but still promising

    Printing the Testpage from http://www.google.com/cloudprint/learn/ works like a charm – unfortunately I get an error page printed whenever I try to use the cups printer created by cupscloudprint!
    What I get is:

    PWG ERROR – URFPWG Decoding Fail
    POSITION: 0×2333 (9011) <– that line differs a lot of course…
    SYSTEM: src/xl_dec
    LINE: 757
    VERSION: SPL-C 5.59.01 06-19-2013

    I am using Fedora 20 – do I have to use any ppd files for the printer to get it working for cups?
    as Google is handling my Samsung printer just fine, I suspect the error elsewhere…

    any idea?

  27. Hi Chris,

    That seems to be a unique error, but I’ve found a page where someone printing using Chromium has a different ‘PWG ERROR’ message here. Does printing within Chromium work for you ( from with the print dialog after setting Chromium/Chrome up with Google Cloud Print )?

    The PPD file that CUPS Cloud Print sets for your printer ( should be called something like ‘cupscloudprint:account:printername.ppd’ when listed with the ‘lpinfo -l -m’ command ) should be correct.

    Thanks

  28. Hi Simon,

    Thanks a million for this.

    Just installed on Mac OS X Mavericks. I was having trouble printing from Mavericks to my Home and office printers connected via USB to Windows machines. So I have set up cloud print via chrome on those machines and so far it is working like a charm.

    Just a few comments:
    1. While installing, it said env: /usr/bin/python2 not found. I worked around this with the command sudo ln -s /usr/bin/python /usr/bin/python2
    2. Suppose I add one more printer to my Google cloud print account, how do I install that printer in Mavericks? Do I run the set up Python script again and choose printers to install one by one?

    Thanks and regards

    Vivek

  29. When trying to install, I get the following error


    Downloading Packages:
    warning: rpmts_HdrFromFdno: Header V4 RSA/SHA1 Signature, key ID c5541d9d: NOKEY

    Public key for cupscloudprint-20140308-1.noarch.rpm is not installed

    Installing on centos

  30. When setting up cups cloud print with the setupcloudprint.py, I get the following error RuntimeError: failed to connect to server

    How do I fix this?

  31. Hi Vivek,

    Great, glad it is working for you.

    1. This should be fixed in the next version, that workaround is the simplest one for now.
    2. You should just need to re-run the setup script and it should detect new printers and add them ( just say ‘Y’ to ‘Add all Google Cloud Print printers from src to CUPS (Y/N)?’, it will only add the new printers, and won’t duplicate any existing ones ).

    Thanks

    Simon
