IRB Printers

The IRB provides affordable printing to students and employees via  CUPS (Common Unix Printing System).

Students are given access to all public printers, employees to every printer.

Pricing & Charging Accounts

The IRB Printing system is run in cooperation with the Fachschaft Mathematik Informatik, who handle the money deposits while we handle the technical systems. This Fachschaft can open a printing account for you, from which money is debited when your print on our systems.

Printing requires a positive balance. To view current balance and past print jobs, visit druckerseiten.de

Pricing

 
Print Type Cost per page
black, draft 2 cents1
black 4 cents
color, simplex 20 cents2

1. No quality guarantees are made for draft printers (*-draft). Use a different printer if quality is of importance.
2. All pages printed as color pages cost this much, regardless of the amount of color actually present.

Printing with Linux

preparation of your own device

To be able to send a printing job to our CUPS server, your local CUPS client needs to

  • support Kerberos Authentification
  • have our CUPS server configured

First of all, you must ensure that you have a valid Kerberos ticket. How to set up Kerberos is described here.

If this is done, enter the following in your /etc/cups/client.conf:

"ServerName cups.cs.uni-paderborn.de"

This file is usually empty. You can create the file if it  does not yet exist.

Afterwards, restart your local CUPS clients. You should be able to print now.

from the Command Line

$ lpr -P <printer name> -o <options> <document>

Options

Additional options have to be appended with -o. There has to be an -o for every option. Options may vary for different printers. Some examples: 

  • Set margin: -o page-left=NN (left can be exchanged with right, top, bottom. "NN" is a placeholder for points (1 point = 0.35cm))
  • Automatic line break: -o wrap=true
  • Explicit use of a specific paper slot: -o InputSlot=Lower (it is in fact a little more complicated, because every printer comes with its own names for different slots)

Example: Printing a text file with around 1cm left margin and automatic line break

lpr -P compinet -o page-left=70 -o wrap=true datei.txt

It becomes cumbersome quite fast to use these options. If a lot of settings are to be made, it is advised to use a graphical lpr substitution like kprinter (see below).

Duplex-Printing

Duplex-printing is done by special printer instances. Every printer "<printername>" comes with a second entry "<printername>-dup" which can be used to print duplex.

It is not required to set duplex printing in the options manually.

Creating instances

It can be useful sometimes, to create an instance for frequently used options. It is possible to create such instances using lpoptions. They are saved at ~/.lpoptions.

  • Show options: lpoptions -p <printername> --- Lists all possible options of a printer in its default settings.
  • Setting resolution (DPI): lpoptions -o ColorModel -o Resolution=600dpi -P <printername>
  • Set instance: lpoptions -p printername/instancename -o Option1 -o Option2 ... -o OptionN --- Setting your own instance (old instances will be overwritten!!!).
  • Show instance: lpoptions -p printername/instancename
  • Delete instance: lpoptions -p printername/instancename -x

Deleting jobs

Jobs can be cancelled using the Linux command line.

Printing with Windows

from your own device
  1. To add a new CUPS printer, open the Start Menu and in the search field enter "cupsad.cs.upb.de" (on older Windows System, you first need to select "Run")
  2. You need to establish a VPN connection before you can access \\cupsad.cs.uni-paderborn.de. Use your IMT username and password if you are asked for credentials; make sure that you prefix your username with "ad\". Now double-click the desired printer.
  3. If you receive a message that no driver has been found in the network, dismiss the Dialog with "OK" and select a proper driver manually.
  4. You find the type of the printer at https://cupsad.cs.upb.de/printers/  First select the vendor on the left (normally Kyocera or HP) and then the model on the right. If the model is not in the list, try a "similar" printer (eg. "Kyocera FS-3900DN" instead of Kyocera FS-3830N)
  5. Confirm with "OK". The printer should now be ready for use.
from Computer Pools & Employee PCs

Printers must be installed manually when using Windows.

When selecting printers in CUPS, choose the one with the highest number.

  1. Select Start Menu -> All Programs -> Printer <printer name> CUPSAD
  2. The printer now becomes available in the standard print dialog.

Printing with Mac OS

preparation (>= Mac OSX 10.7)

CUPS access is managed via IMT Active Directory. You must connect at least once via the Explorer to allow authenticated printing:

Proper printer drivers are required to print from Mac. Kyocera offers one here for our Kyocera printers.

Add the printer in question to the category "Printers & Scanners" in your system settings. Cick the "+-" symbol below the Printer listing and choose "Advanced". Use thesetting seen in the screenshot below.

 

Druckprobleme ab MacOS 10.14 (26.10.2018)

Mit macOS 10.14 führen Drucker auf manchen Kyocera-Druckermodellen, wie z.B. dem Kyocera P3055DN dazu, dass nur Zeichensalat bzw. PS-Sourcen gedruckt werden. Aktuell ist uns hier kein aktueller Druckertreiber von Kyocera bekannt, es kann aber unter Verwendung des Allgemeinen PCL-Drucker-Treibers (Generic PCL-Printer) gedruckt werden. Dazu muss der alte Drucker gelöscht und ein neuer Drucker hinzugefügt werden, wie im nächsten Abschnitt zu den Problemen mit macOS 10.13 beschrieben wird.

Druckprobleme ab macOS 10.13.2 (6. Dezember 2017)

Seit dem OS Update auf macOS 10.13.2 gibt es Probleme zwischen Apple Geräten und allen gängigen KYOCERA Druckern.
Das Fehlerbild ist vielfältig und tritt unregelmäßig auf. Bei KYOCERA ist diese Problematik schon bekannt und es werden Treiber Updates zu Verfügung gestellt.

Zu finden sind diese unter:

www.kyoceradocumentsolutions.de/index/serviceworld/downloadcenter.html
einfach den aktuellen Treiber installieren und alles sollte wieder wie gewohnt funktionieren.

Achtung!

Bei einigen Geräten muss der gewünschte Drucker einmal entfernt und neu hinzugefügt werden.

Drucker entfernen

Den Drucker löschen Sie in den Systemeinstellungen über die Rubrik "Drucker & Scanner". Wählen Sie den zu löschenden Drucker aus und klicken Sie auf das "-"-Symbol unterhalb der Druckerliste.

Drucker hinzufügen

Den Drucker fügen Sie in den Systemeinstellungen über die Rubrik "Drucker & Scanner" hinzu. Klicken Sie auf das +-Symbol unterhalb der Druckerliste, wählen Sie den "Erweitert"-Button (Advanced) fügen Sie den Drucker analog zu den Einstellungen im folgenden Screenshot hinzu.

Sollte der Button nicht in der Symbolleiste vorhanden sein, können Sie diesen Buttons hinzufügen, indem Sie per ctrl + Mausklick neben die anderen Symbole klicken,  "Symbolleiste anpassen wählen" und den fehlenden Button in die Leiste ziehen.

Special Print Jobs

Scanners

There are two scanner available for use. This service is provided free of charge.

  • E1.129 Flatbed Scanner
  • F2 copier & scanner

A flatbed scanner is avaliable for use in the guru office at the main campus during our office hours.

The copier on F2  can scan your documents and send them to an EMail address. Choose the menu item "Senden" on the printer panel for further options.

Plotter prints (up to DIN A0)

Our plotter is a HP Designjet Z6100ps 42", and is added as a Network printer in Windows:

  • Adresse: \\cupsad.cs.uni-paderborn.de\rednix-a0

The required driver is the latest HP Designjet z6100ps 42in Photo HPGL2, which, if not already available, may be downloaded from the HP-Support pages.

  • Powerpoint Files can not be effectively resized to DIN A0 with acceptable results, due to formatting issues.
  • Using Coreldraw and raw Bitmapped (.bmp) as backgrounds in DIN A0 consumes considerable storage, which the computer may not possess. Adding the pictures shortly before printing may speed up your workflow.
  • Mathtype works only up to version 9 of Coreldraw. Later versions break fonts on import.
  • When making test prints in smaller sizes, use a color inkjet rather than the fa[12] color laser. Experience shows that the resulting colors are closest to the DIN A0 plotter.
  • University Paderborn Corporate Design is available here.
  • A paper cutter is provided near the plotter. Please handle it gently during use.
  • PDF can provide an acceptable intermediate format. See the PDF guides further up the page for help.
