Print from Linux

This guide is for users at DTU Compute only

Printing from department servers (e.g. linuxterm, thinlinc, hms1, ...) does not require any setup. Printers have already been installed.

System wide solution (have root access)

• Open a terminal and type sudo system-config-printer and hit Enter.
• Add a new printer and use the URI ipp://cups.compute.dtu.dk/printers/cm321018a (replace cm321018a with the printer you want, see list of printers)

System wide solution - stationary PC (have root access)

Note: If you are printing to other printers that DTU Compute department printers, you should not use this method.

You need root privileges in order to configure this and the change will apply for all users of the computer

sudo cp /etc/profile /etc/profile.orig
sudo echo 'CUPS_SERVER=cups1.compute.dtu.dk/version=1.1' >> /etc/profile
sudo echo 'export CUPS_SERVER' >> /etc/profile

Reboot the computer. After the computer is rebooted you should now how a list of printers to use. For more information about the printers have look here.

If you get a dialogue box about authorization failed containing fields to enter username and password, DO NOT enter your password as it is not required and it sent unencrypted over the network. Just click "OK" and everything will be fine.

User only solution without root access (commandline)

Here root access is not needed. The change will only take effect for the user logged in.

cp ~/.profile ~/.profile.orig
echo 'CUPS_SERVER=cups1.compute.dtu.dk/version=1.1' >> ~/.profile
echo 'export CUPS_SERVER' >> ~/.profile

Log out of the system and log in again. The system can now see all available printers.

If you get a dialogue box about authorization failed containing fields to enter username and password, DO NOT enter your password as it is not required and it sent unencrypted over the network. Just click "OK" and everything will be fine.

Note: This might not work for some graphical applications not started from the command line.

User only solution without root access (GUI)

If you want to be able to easy switch between DTU Compute's print server and e.g. a home printer, then follow this guide.

• Open a terminal and type system-config-printer and hit Enter.
• On Ubuntu go to the global menu for the just opened program and click Server and then select Connect....
• As "Cups server" type: cups.compute.dtu.dk and click Connect.

You should new see a long list of printers. Right click on the one that you want to use, and select Set as default.

Adding a home printer

Is done by opening a terminal and type system-config-printer and hit Enter. From here click Add and follow the instructions.
