Network Printing With Ubuntu


Ubuntu supports printer sharing over networks, so you can print from your Ubuntu machine, your Windows machine, etc, to another Ubuntu or Windows machine that has a printer attached (ie a “Ubuntu print server” or “Windows print server”).



Ubuntu uses the Common UNIX Printing System (“CUPS”) to handle printing. CUPS uses the Internet Printing Protocol (“IPP”) as the basis for managing print jobs and queues. Other protocols are also supported (LPD, SMB, AppSocket a.k.a. JetDirect), some with reduced functionality.

CUPS printer configuration and management is handled by the Printer Admin utility launched from the Gnome menu – System -> Administration -> Printing (If the menu item does not exist you need to add the command system-config-printer to the menu). Also IPP provides web services so after you have configured CUPS appropriately, you can access the printers and jobs via your web browser.

When a locally attached printer is defined, eg using the Printer Admin utility, that printer is automatically published from this “print server” host to the network, depending on the server directives in the CUPS configuration file. A remote Ubuntu “client” host can then be able to see and use the printer attached to the server. The network printer automatically appears in the client’s Printer Admin utility. It simply pops up if CUPS is up and configured correctly and disappears if you stop CUPS at either the Print Server or your local machine.

Ubuntu print server

The Print Server is the Ubuntu computer that is directly connected to the printers.

  1. On the server machine (the one the printer is attached to), open System -> Administration -> Printing (If the menu item does not exist you need to add system-config-printer to the menu). . This will open the Printer Configuration window.system-config-printer

  2. Select Server in the menu bar, and then Settings. This will open the Basic Server Settings window.

  3. Check the second box:

    Publish shared printers connected to this server If this computer acts as both a Print Server and a client (it does need access to a printer connected to another computer), select also the first box, “Show printers shared by other systems”.Server-setting

  4. OK

  5. Right click the printer and check the Shared option, if not checked yet

  6. Check that users that you want to be able to use the printer are not excluded. See Properties>Access Control. The default settings may be set to “deny printing for everyone except …”inkjet_settings1                you might want to “allow printing for everyone”.


    Ubuntu print server compatible with Windows (Samba)

    If your Ubuntu print server shall be able to work also with Windows clients, you must first make sure that the SAMBA package is installed (e.g. using Synaptic package manager). Then, do a little configuration change to SAMBA. In brief, you must uncomment the following lines in /etc/samba/smb.conf – open terminal and run:

    gksudo gedit /etc/samba/smb.conf

    In the [printers] section:

       browseable = yes
       guest ok = yes

    When done, restart Samba:

    sudo service smbd restart
    sudo service nmbd restart

    There is a dedicated page in the official documentation which gives more details.

    Also, one would want to allow the following ports through a firewall (ufw for example) via:

    sudo ufw allow 139/tcp
    sudo ufw allow 445/tcp
    sudo ufw allow 137/udp
    sudo ufw allow 138/udp

    For more on this, please see here.

    Printing from Ubuntu

    Now let’s configure the client (the Ubuntu computer from where you want to print):

    1. System -> Administration -> Printing

    2. Add – Network printer

      1. Click Find network printer

        • Specify the host IP address or name. (It may also work without, try) (IP address worked for me, hostname did not.)
        • Click Find

      2. Printers on the target machine should be found, no matter whether they are connected using CUPS or SAMBA.
        • BUT if both protocols are available, e.g. because you have shared your printer on a Linux box both using CUPS and Samba, prefer CUPS (ipp://) over Samba (smb://), because you won’t be prompted to install a driver in general.findNetworkPrinterScreenshotYou **may** be prompted to select a driver. Select your model in the list.
          • (to be done) What to do if driver is not in the list
        • Printing from Windows


          Once your Ubuntu print server is set up using SAMBA as described above, you can add the printer in Windows as follows:

          1. Start
          2. Devices and Printers
          3. Add a printer
          4. Add a network, wireless or Bluetooth printer
          5. Click The printer that I want isn’t listed (unless a miracle happens)

          6. Enter the address manually (\\servername\MyPrinter). Be sure to respect uppercase/lowercase.windoze-addprinter-step1

            windoze-addprinter-step2Note that searching or browsing for printers in Windows is notoriously unreliable, as it heavily depends on the network setup. Therefore, it is recommended to enter the printer address manually as shown.

            Windows will then probably complain about a missing driver, and offer you to choose one manually. This is the easiest option, so select your printer manufacturer and model from the dialog box. (Alternatively, the Samba configuration could be improved so that the driver would be automatically downloaded.) If your printer model isn’t listed, you may try the “Generic” printer.

            Tips: You can avoid intermediate SAMBA buffer using direct connection to CUPS/IPP Ubuntu server from Windows workstation. You should manually specify “http://hostname:631/printers/MyPrinter” IPP URL and select printer driver.

            Windows print dialog window (Ctrl-P) can take long time (about 30 seconds) to appear. You can reduce the connection time to CUPS IPP printer by disabling option Automatically detect settings in “Control Panel/Internet Explorer -> Internet Options -> Connections -> LAN settings”.


            1. Bypassing firewall.

            If there is an firewall either on print server or the client side, there might appear a communications problem. Use this command to update the firewall to get through.

            iptables -A INPUT -p tcp –dport 631 -j ACCEPT

            • This rule is used for IPP only. If you’re using other protocol, such as SAMBA, you have to adapt.

              You might need to use this rule on both sides (server & client) if the firewall is being used on both of them. To apply this rule after each start/restart of the system, use /etc/rc.local .

            2. Networking issues.

            Be careful about using different network masks/subnets on your network where you would like to share the printer.

            If the subnets differs, e.g. on the print server there would be a /24 ( netwok mask configured, and e.g. on the clients there would be a /16 ( network mask – perhaps provided by the DHCP server, this might cause a problem that clients won’t be able to detect any shared printer on the server, even if other communications between print server and clients would be possible (e.g. ICMP, ssh) and successful.

            If such situation happens, you have to unify the network masks/subnets on all of your stations, e.g. use /24 (255.255.255.

            3. IP address

            Generally, it is a good idea to assign your print server a static IP address. Instead, using its host name is also possible, but functionality will then depend on proper configuration of your home router, name service, etc.

            4. IPv6 Windows (since XP) can print over IPv6 to Ubuntu Linux (tested between Windows XP SP3 and Ubuntu Linux 8.10). Make sure both the Windows and Ubuntu have IPv6 connectivity. You should tick “Allow Printing from the Internet” on the Ubuntu machine. Then use the URL (which resolves to IPv6) of the Ubuntu machine as described above.

            5. Mac OS X 10.5.

            Will not find your network printer unless you go to the terminal and run cupsctl BrowseRemoteProtocols=cups (see the CUPS 1.4 documentation at After doing so, you may need to set the network printer as your default printer for it to show up in program “print” menus.

How to install Elance Tracker in latest Ubuntu 14.04


Elance Tracker app uses Adobe Air and as Adobe has stopped Air support for Linux (the latest supported version is 2.6) – it became problematic to run Air apps on Linux.
You can find a lot of manual allover the Web how to solve different issues and install Air on Linux (like linking etc.), but with Ubuntu each new version brings less compatibility.
On Ubuntu 13.10 for a long time I was not able to install Adobe Air in any way. Only one manual from helped me to figure it out.

My previous manual using Wine was not correct. Sorry for that, with Wine you can install and run Tracker, but time and screenshots are not being tracked. So it is useless.

  • Here is one quick script. Save it as
apt-get install libgtk2.0-0:i386 libstdc++6:i386 libnss3-1d:i386 lib32nss-mdns libxml2:i386 libxslt1.1:i386 libcanberra-gtk-module:i386 gtk2-engines-murrine:i386
cd /tmp
apt-get download libgnome-keyring0:i386
dpkg-deb -R libgnome-keyring0_3.8.0-2_i386.deb gnome-keyring
cp gnome-keyring/usr/lib/i386-linux-gnu/ /usr/lib/i386-linux-gnu/
ln -s /usr/lib/i386-linux-gnu/ /usr/lib/i386-linux-gnu/
ln -s /usr/lib/i386-linux-gnu/ /usr/lib/
ln -s /usr/lib/i386-linux-gnu/ /usr/lib/
chmod a+x AdobeAIRInstaller.bin
rm ./AdobeAIRInstaller.bin
rm /usr/lib/
rm /usr/lib/
  • Make it executable sudo chmod a+x
  • And run sudo ./ (during running Abode Air wizard will appera, you should go through it)
  • Then download Elance Tracker for Linux as usual and install it in normal way

Creating new virtual host while using Xampp in Ubuntu (Linux)

I need this stuff quite often. Every time i need to create a new virtual host in Ubuntu i have to google/search to find this solution as i cannot remember these paths properly. I am posting it here for quick reference for myself. Bookmark it for yourself (which i am going to do after i have finished posting it ;))

1. Enable virtual hosts by editing httpd.conf, if it is not enabled already. Once you enable it you can skip this step next time.

sudo gedit /opt/lampp/etc/httpd.conf

Find #Include etc/extra/httpd-vhosts.conf and remove the # to un-comment this line

Include etc/extra/httpd-vhosts.conf

2. Add new virtual host by opening the httpd-vhosts.conf file

sudo gedit /opt/lampp/etc/extra/httpd-vhosts.conf

Usually, by default there are two virtual hosts in this file. You can edit one or create new one by copy-pasting one of them. The required entries are DocumentRoot andServerName

<VirtualHost *:80>
DocumentRoot /opt/lampp/htdocs/mysite_folder
ServerName mysite.local
ServerAlias www.mysite.local
ErrorLog logs/mysite.local-error_log
CustomLog logs/mysite.local-access_log common

3. Next, you will need to tell Xampp server where to find the address you added above:

sudo gedit /etc/hosts

Add the following line: mysite.local

4. Restart xampp server by doing

sudo /opt/lampp/lampp restart

5. Type http://local.mysite in browser’s address bar and it should work.

How to install ubuntu 14.04 using wubiguide

What is Wubi?

Wubi is an officially supported installer for Windows XP, Vista and 7 users that allows Ubuntu to be installed and uninstalled in a safe, easy way as with any other Windows application.

What about Windows 8?

At this time, Wubi does not work with Windows 8 default boot-loader. Thus at this point Wubi would not work on a new Windows 8 machine. You would be able to install, but not reboot into Ubuntu.

If you upgraded to Windows 8 and are using BIOS firmware, Wubi does work, but do not enable hybrid-sleep on Windows 8.

How to use this guide

Please note that this guide is only for issues directly related to the Wubi installer; for general Ubuntu questions please use appropriate resources such as the official Ubuntu documentation, the Ubuntu Forums, or the Ubuntu Guide.

You might also be interested in the Ubuntu Forums Installations & Upgrades section.


Wubi uses a virtual disk that is sensitive to forced shutdowns. If Ubuntu appears to be frozen please refer to: How to reboot cleanly even when the keyboard/mouse are frozen

How do I download Wubi?

Download Wubi from the Ubuntu Windows Installer cdimages page; this will download the latest version. You can download other versions from the Ubuntu pages on, e.g. 12.10, look for wubi.exe at the bottom of the page. Wubi is also included on Ubuntu Desktop and Kubuntu CDs.

How do I install Ubuntu?

Run Wubi, insert a password for the new account, adjust other settings such as the disk space, and click “install”.

The installation process from this point on is fully automatic.

The installation files (approximately 700MB) will be downloaded and checked, after which you will be asked to reboot.

Do so and select Ubuntu at the boot screen. The installation will continue for another 10 to 15 minutes and the machine will reboot again.

That’s it. Now you can select Ubuntu at the boot screen and start using it.

Screenshot of the installation screen

The standard installation has default settings that should work on most hardware.

How do I select whether to run Windows or Ubuntu?

You can choose to run Windows or Ubuntu at the system boot screen.

Screenshot of the boot screen

How do I install Wubi on a machine with no Internet connection?

Wubi also works with physical Ubuntu Desktop Live CDs. Wubi.exe is available in the root folder of the CD.

If you do not have a CD, try to find a computer with Internet access, and download both Wubi.exe and the required Desktop ISO from the same location (the release has to match):

Copy both files into the same folder on the machine with no Internet access and run the Wubi executable.

Where do I find older versions of Wubi?

Older versions of Wubi can be found on the SourceForge page.

How can I use a manually downloaded ISO?

You need to download the DESKTOP CD ISO of the appropriate version. Place the ISO in the same folder where you have wubi.exe and then run Wubi. For example, Wubi 11.10 requires the 11.10 DESKTOP ISO, available here.

Note that you need a DESKTOP CD ISO. A DVD ISO may not work (except for Edubuntu). Alternate ISO files are not supported.

Why is the AMD64 version of Ubuntu being downloaded and installed?

The machine you are trying to install Ubuntu on is 64 bit. The AMD64 installation is appropriate for all 64 bit architectures, no matter if they are AMD or Intel.

Can I force Wubi to download and install a 32 bit version of Ubuntu?

Yes. Either pre-download the appropriate 32 bit ISO manually and place it in the same folder as Wubi.exe or start Wubi from the command prompt with the “–32bit” argument.

To modify arguments without using the command prompt, right-click Wubi.exe and select “Create Shortcut”. Then right-click the shortcut, select Properties, and modify the Target line, for example: “C:\Documents and Settings\<user>\Desktop\wubi.exe” –32bit

Can I force Wubi to install if I have less than 256MB of memory?

Yes. start Wubi with the argument “–skipmemorycheck”. The installer may not work in such conditions.

Can I force Wubi to install even if I have less than 5GB of free disk space?

No. From release 11.10, 5GB is required as a minimum including enough space to store the ISO. On older releases, start Wubi with the argument “–skipspacecheck”. Even on older releases, you’ll still require 3GB of space plus room for the ISO. Pushing this limit too hard may cause errors.

Can I force Wubi to skip the md5 checks?

Yes. Start Wubi with the argument “–skipmd5check”.

Which Operating Systems are supported?

Windows 7, Vista, XP, and 2000 are known to work with Wubi. Windows 98 should also work, but has not been thoroughly tested. Windows ME is not supported. Linux is supported through Lubi.

What happens if the installation is interrupted?

If the installation is interrupted for any reason, you will have to run Wubi.exe again from within the Windows installation (which in turn may force you to uninstall first).


Upgrading from 12.04 to 12.10 is supported. FIXME other

Upgrading from releases 10.04 and later is supported. Please review the applicable release notes before hand. Ensure you have sufficient free space, and consider backing up the \ubuntu\disks directory (from Windows) in case there are any errors, or you prefer to revert to the old release.


How do I uninstall Wubi?

Run the uninstaller in “Control Panel > Add or Remove Programs” for Windows XP or lower or “Control Panel > Programs and Features” for Windows Vista or Windows 7. Alternatively, you can run: C:\ubuntu\Uninstall-Ubuntu.exe.


If the uninstaller fails, try downloading and running Uninstall-Ubuntu.exe.

How do I manually uninstall Wubi?

Remove C:\ubuntu and C:\wubildr*

In Windows XP you need to edit C:\boot.ini and delete the Ubuntu/Wubi line. Alternatively you can modify the boot menu via Control Panel > System > Advanced > Startup and Recovery and pressing “Edit”. For Windows 98 you have to edit C:\config.sys and remove the Wubi block. For Windows Vista/7, you can use the built-in bcdedit command or install EasyBCD to edit the boot menu. To use bcdedit, run cmd.exe as an administrator, then enter bcdedit to show all boot entries, note the {GUID} specified for the Ubuntu entry, and then remove it: bcdedit /delete {GUID}

To remove Wubi from the add/remove list, delete the registry key: HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall\Wubi

An easy method of removing this registry key is to paste the following text into a plain editor such as Notepad, close and save the file as something like removeWubiKey.reg (you may wish to go to Folder Options > View and disable the “Hide file extensions for known file types” option to check that the .reg extension has been applied correctly). Then you can perform the rest automatically by opening the file in the normal Windows manner, or choosing the “Merge” option from the right click context menu. Note: The formatting is rather strict, so copy the text exactly for best results. You may need to be logged in as the administrator to delete the key, depending on the version of Windows you are using. User Account Control in Vista may also ask for permission, in the typical fashion.



After deleting the registry key, Ubuntu may still appear in the program list. If this is the case, you may be asked if you would like to remove the item from the list.

How do I reinstall Wubi?

Run Wubi.exe again. Wubi will detect that there is an existing installation and you will be offered an option to uninstall. You may want to backup the installation files (the ISO) in order to avoid having to download them again. Note that when you reinstall, the system virtual drive (root.disk) is reset.

How can I make a backup of my Wubi install?

The easiest method is to to simply copy the root.disk to an external medium. In the event that something goes wrong, copy the root.disk back to the Ubuntu folder on the Windows drive. Note that this is not the most efficient method (since it copies the whole root.disk rather than specific data/settings) but it is effective.
