Printing under Linux

If you use a Linux computer in the IRZ pool, it has already been set up to use the print server linuxprint.informatik.uni-hamburg.de. You do not need to configure printers individually.

If your workplace computer runs Linux in your office, you can set up printers in various ways. The first two options provide all printers configured on linuxprint and will appear in your printer selection. If this becomes too cluttered for you, you can use the third option.

1. When the computer is used exclusively within the Computer Science network, it should be configured as a client of linuxprint. To do this, add the following line as the only entry in the file /etc/cups/client.conf:

ServerName linuxprint.informatik.uni-hamburg.de

Afterward, all printers offered by linuxprint will be available on your computer. The local CUPS daemon running on your computer can then be stopped and does not need to be started again.

2. If your computer is used as a mobile device and you want to install local printers as well, you should configure the local CUPS daemon to also offer printers from linuxprint. To do this, insert the following line into the file /etc/cups/cups-browsed.conf:

BrowsePoll linuxprint.informatik.uni-hamburg.de:631

After restarting the printing system with

service cups restart (for Debian/Ubuntu) or
/etc/init.d/cups restart (for openSUSE)

all printers from linuxprint will be available alongside your local printers. Please note that it may take a few seconds for all printers to be displayed.

3. For older CUPS versions (version 1.5 and earlier), you need to edit the file /etc/cups/cupsd.conf.

Alternatively, you can set up only the specific printers you need. For this, add them to the file /etc/cups/printers.conf and know the name of the respective print queue. Here is an example for setting up the printer d116_sw:

<Printer d116_sw>
DeviceURI ipp://linuxprint.informatik.uni-hamburg.de/printers/d116_sw
</Printer>

Then, restart the printing system with

service cups restart
