Printing

Contents

General

Printing is possible via the common software interfaces(e.g. evince, okular, libreoffice, etc.). Please note, that you need to send the printing command only once. If there is a problem, causing the printer to stop working properly, it is unlikely to be solved by pressing "print" multiple times and you might end up with multiple copies of the same document after the problem is solved.

Here you can find a list of printers and their status

Printing via command line

The basic commands:

  • Print document
    lpr <FILENAME>
    
    or
    
    lpr -P <PRINTERNAME> <FILENAME>
    
  • show standard printer:
    lpstat -d
    
  • set standard printer:
    lpoptions -d <PRINTERNAME>    
    
    The settings will be saved in
    
    ~/.cups/lpoptions 
    
    
  • Display the current print jobs of the print server:
    lpstat [-t]
    
    bzw.
    
    lpq -P <PRINTERNAME>
    
  • delete print job:
    cancel <JOBID>
    
    or without <JOBID> to delete all your print jobs.
    
  • Cancel print XY
    cancel XYZ
    
  • show printlimit
    printlimit
    

    oder
    repykota --printer printers
    

Many Types of files will be recognized automatically, eg Text(ASCII), PostScript (ps), dvi, pdf and jpg. Every other File has to be printed direct from an application (eg LibreOffice Documents) or has to be converted. More information you can get via man cancel, man lpstat, man lpoptions and here

Direct Printing

If printing is not working, please enter the following command to print directly:

lp -d Nameoftheprinter Inputfile.ps/.pdf

Nameoftheprinter should be replaced by the name of the printer, while Inputfile.ps/.pdf should be replaced by the type of document *.ps or *.pdf.

Known problems

Some PDF-Files aren't printed.
Solution: Expression has to be changed in ps file with option Postscript level2. Then apply ps2ps to the resulting file. Print the result with lpr <file name>.

Printer Names

A default printer is usually assigned to each user. If one is available, this is the local printer at your work station. Otherwise, the default printer is called "psout". The local printer in a work station always has the same name as the work station itself. If you are not sure which printer is set as your default printer, it might be helpful to enter von echo $PRINTER.

List of printers at the Institut

Only the publicly accessible printers and no workplace printers are listed.

Printer name Location Type Colour Double sided IP Comments
pgrad Graduiertenkolleg Lotzestr HP LaserJet 4015dn x 89
pneben Annex Building HP LaserJet 4015dn x 88
kopier Main Building Copy Room Ricoh x 83 =doppel

color3 Main Building Room 008 HP Color LaserJet 5550dn x x 82 A3 color printer
color4 Main Building Room 008 Dell 5110cn x 77 A4 color printer

Also, now one sided printing can be done on two-sided printers. The queue then has the additional 'single' option, e.g. "doublesingle" or "doppelsingle". The double-sided printers can print documents in different binding directions. The additional keyword book allows printing as it is needed for an A5 book.

Quota

Students

There should be a little window in your account showing your money. Every semester, there is a free 10 Euro quota. If you need additional money on your account, you can load your personal quota at the StudIT office (room 209), the quota for 200 extra pages is 5 Euro.

Employees and PhD Students

There is no quota, but we ask you to avoid unnecessary printing to save the environment.

Additional Information http://wiki.student.uni-goettingen.de/support/drucken

Uncollected Printing

Print jobs processed on the printer in room 008 are collected regularly and are sometimes stored in the brochure holder located next to the printers on the wall. Before reporting a supposedly lost print job, look there.

Color Printing

For color printing, you can use printers: "color3" (for A3) and "ckopier2". ckopier2 is in Office (room 209) and should only be used outside of office hours. However, the prints on ckopier2 are the cheaper.

Poster Printing

We have a A2 / A1 Inkjet Poster Printer. It is operated only by the system administrator. The document should be available as PDF at least 4 working days before. The printer is able to enlarge A4 size to A2 or A1. If the poster contains images in a pixel format (jpg, TIFF, png) you can achieved slightly better print quality by changing the document into the target format.

If you wish to print a poster, you should indicate this in a Support-Request as early as possible. At least 4 business days before printing. Then if there are problems is enough time to print the poster document at the GWDG.

A0 prints must be carried out at the GWDG. An account (Eduroam) is needed to do this. Also, plenty of [Druckarbeitseinheiten] must be available.

Request at:

http://www.gwdg.de/index.php?id=41

An A0 poster on the queue "Poster" costs 0.55 AE's. A poster high quality of Canon poster printer costs 0.7 AE's. These posters have to be registered with us and will be printed and billed in the presence of the customer by us.

Restart of the print server

The print server will restart from time to time. All hanging jobs are deleted then.

Printing with the laptop running Linux/Macintosh

After LION OSX (10.7 and higher)

Cups works differently there.

System Control
 Printing and Scanning
 + (Enter admin password)
  IP 
   134.76.82.54 (names don't work)
   Choose ipp-Protocol
   printers/<desired printer>
   Location - Set if you want
   Printing driver: always Postscript

http://lapserv.maths.cam.ac.uk/docs/osxprint108.html

Alternatively you can use the Bonjour Protocol:

Before LION OSX (before 10.7) / Linux

Variant 1: Only public printers

If you won't connect your computer to printers other than the ones managed by the printing server of the Mathematicial Institute:

  1. Go to the file client.conf (create it if it isn't there):
    Debian: /etc/cups/client.conf
    Mac: /private/etc/cups/client.conf
    
  2. Open it as root and look for the entry #ServerName myhost.domain.com (if it isn't there, just insert the next line).
  3. Replace it with: ServerName prtsrv2.uni-math.gwdg.de and save.
  4. Restart cups: Debian: "/etc/init.d/cusys restart" or "service cups restart" Mac: No action needed

Variant 2: Public and private printers

If you also want to use printers other than the ones managed by the printing server of the Mathematical Institute:

  1. Open the following file with a text editor (as root/admin):
    Debian: /etc/cups/cupsd.conf
    Mac: /private/etc/cups/cupsd.conf
    
  2. Find the entry
    Browsing Off
    

    and change it to
    Browsing On
    
  3. Add the entry
    BrowsePoll prtsrv2.uni-math.gwdg.de:631
    
  4. Restart Cups:
    Debian: /etc/init.d/cusys restart
    Mac: No action needed
    

Root under Macintosh
Login as an Administrator and enter sudo passwd root. Then enter the password
Or sudo bash then enter the password.

Printing with a laptop running Windows

I. Windows XP und CUPS as an example

You want to use the printer persatz. Find it in this list:

https://prtsrv2.uni-math.gwdg.de:631/printers/

Now the CUPS printer is configured in Windows XP.

"Add Start / Printers and Faxes / Printers" 
"Next" 
"Network printer or printer that is connected to computer" 
"Connect to a printer on the Internet or home / office network" 
URL is here

https://prtsrv2.uni-math.gwdg.de:631/printers/persatz

and click "Continue" ("Weiter")
Now select the appropriate printer driver ...
(In our example, the model of printer HP LaserJet 4100)
  If you want to use the printer as the default printer, you should select the next "Yes" - if not then "No" 
"Finish"
