====== Printing ======
The department utilises a CUPS-Server (''cups.math.uni-hamburg.de'') with SMB/CIFS (aka "Samba") to serve printing for the Windows community. Printernames (actually queues) are composed from cl (color laser) or l (laser) followed by the room number. A letter at the end denotes multiple printers in one room.

The address of each network-printer takes the following form:\\
''<nowiki>ipp://cups.math.uni-hamburg.de/printers/QUEUE</nowiki>''\\ 
''<nowiki>http://cups.math.uni-hamburg.de:631/printers/QUEUE</nowiki>''\\
(Both adresses are functionally equivalent, in most system only one of the two variants work. Notably: Mac uses only the first form, Windows uses only the second.)

===== Windows =====

==== Using the Samba Port for Printing ====

**Operating Systems:** Windows 7 / 10


==== Installation ====
If connected to via kabel to the university's network, a samba server, delivering printers to Windows systems, can be used. This minimises configuration effort and elimates the need for a separate driver-installation.

  - printers distributed by Samba (SMB/CIFS) can be reached using the [[wp>Path_(computing)#Universal_Naming_Convention|UNC]] path ''\\print''
  - by entering it in the __adress field of the Windows Explorer__
  - then select the printer (l or cl followed by the room-numer) by double clicking...
  - when you are asked "do you trust this printer", answer with "Install driver".
  - in the advanced printer options change "Letter" to "A4"

Otherwise the configuration can be done via the Windows printer and scanner menu.
  - Start -> search for printer and scanner
  - add printer
  - select "printer not enlisted"
  - Enter device URI” http://cups.math.uni-hamburg.de:631/printers/<QUEUE> (where <QUEUE> is one of the printers from the browser list) and proceed
  - select driver for desired printer (the driver might have to be installed previously!)

==== Problem ====
As said above, some of the printers are delivered with "letter" format by default. Go to the prining menu of the respective printer (right click the printer in the printers list of your computer), click advanced, then change "Letter" to "A4".



===== Installing a printer under ubuntu =====
==== GNOME ====

For additional support open in browser:
http://cups.math.uni-hamburg.de:631/printers/

Then in System
  * "System -> System settings-> Printing" (in v11.04 to be found w/ right click on the switch)
  * "Add"
  * "Enter device URI" <nowiki>ipp://cups.math.uni-hamburg.de/printers/</nowiki><QUEUE> (where <QUEUE> is one of the printers from the browser list), then "forward"
  * "Choose Driver", "Select printer from database", 
  * select brand, "forward"
  * select modell and driver (use Foomatic/Postscript if possible), "forward"
  * "Describe Printer", Short name = <QUEUE> (e.g. cl225), Location = Room number, "Apply"
  * print test page
  * abort printer setings

==== KDE ====
Kickoff -> Computer -> System settings -> Printer setup -> New Printer / New Printers -> Other

Enter printer address, follow steps just as GNOME.

===== OS X =====

==== Configuration and Installation of printers ====

In order to install a printer, please follow the steps below:

  * klick onto the 'Apple' - symbol in the upper left corner
  * choose 'System Prefenrences' and then 'Printers & Scanners'
  * click upon the '+'sign
  * in the printer-window choose 'IP' in the upper part
  * then fill in the text-fields as follows:
    * Address: cups.math.uni-hamburg.de
    * Protocol: Internet Protocol-IPP
    * Queue: /printers/<name of the printer> \\ The naming scheme of the printers is: l for laser printers, cl for colour-laser printers, followed by the room number the printer resides (e.g. l112 (laser printer in room 112), cl225 (colour-laser printer in room 225))
    * Name: the same as in Queue
    * Location: GEO - <room number of the printer>
    * Use: Generic PostScript Printer
  * press the 'Add' - button
  * The black and white printers do have a 'Duplex Printing Unit', so please make sure to checkmark the appropriate checkbox.
  * confirm with 'OK'

Repeat these steps for every printer you want to add.
