Accounting

Pages are counted by the printers and quota system. In duplex mode (default), the count of the pages per sheet is increased by 2, even if one side of the sheet is printed. To print a single document so that only one page is counted you should select simplex mode (see below). The banner page that precedes each print job, and usually does not * include the Number of printout pages*.

please print PDF-Files with Document Viewer on Linux

Available printers

you can find more information about Xerox printing Here

The printed pages can be picked up directly from the printers in the small computer hall (directly behind the transition from the large to the small computer hall, left behind the door). If the print-out is not in the printer, it has either already been placed in the shelf (shelf is on the left side of the left printer, or someone has removed your print-out and all other sheets from the printer. Please check if there are any other non-owned print-outs in your stack and please put the foreign print-outs in the bookshelf.

As soon as the Print-out has been printed out or has failed, an e-mail will be sent to the user@ in.tum.de address.

Printing using different programs

Printing with Document Viewer (Linux):

the first clues to the error can already be found here

The print menu can be called up with File → Print (Alternativ: Strg+P).

*First setting:

When your printing for the first time, some default settings need to be changed, otherwise the printers will not be able to print your received job. These are the settings for page size and Paper Scource. Since the printers are loaded with A3 and A4 size paper, error messages sometimes occur if the job was not sent in either format. And since the paper size is clearly linked to the paper source, the default value "Tray 1 " (A3) is not always correct. It should be configured as follows:

* Adjust color:

If you want to print in color, you should not click on Color, but on Advanced. "Automatic" means colored here.

* Send a print job:

As already mentioned in the point Available printers, check that xerhalle is selected before sending your Print job. In this step, you should also select the number of copies that you need.

Troubleshooting

By any Problem ,you should check whether an e-mail about the printing process has been sent to the user@in.tum.de mailbox. . If the print job fails, you will receive a mail with the similar subject * Print order: 'ASDFx' (Job ID 42) FAILED *. In the email you will find more information about why your printing process did not work. If successful, you should get an email like this:

Betreff: Druckauftrag: 'ASDFx' (Job-ID 42) wurde erfolgreich gedruckt

Dear user,

your print job

        A9ROdqbW1A (Job-ID 217121)

has been printed successfully on printer xerhalle1 (Xerox WC 7835 (farbig, doppelseitig)).
You can fetch your printout at

        00.07.023 (kleine Rechnerhalle).

Yours sincerely,
    Rechnerbetriebsgruppe (RBG)

I clicked on print, but the printer just does not print!

Case 1 - Is there enough quota?

just enter in Terminal (in the Computer hall under Applications → Accessories → Terminal)

lpquota 

and check how many pages are available. The output is similar to this:

|===== Abfrage des Druckerquotas fuer 'user' =====|

  Gedruckt (xerhalle1):                253 Seiten
  Gedruckt (xerhalle2):                226 Seiten
  Gedruckt (Summe):                    479 Seiten

Often, problems are occured when you dont have enough quota left to print a document. This must then be purchased again from the student council.

Case 2 - I have enough quota - but no expression

Has the server xerhalle been selected? In some cases, the printer has not been selected, it has been mislaid, or another printer specified, which is located in a completely different location.

Is printing directly from Firefox? In this case, it often helps to select "Print to file … " in Firefox and create a PDF file. This can then usually be printed easily.

Case 3 - I chose xerhalle and quota - but no expression

Just have a look at our helpdesk (small computer hall at the back). It may be necessary to refill paper or it is a different error condition that needs to be resolved by the printers.
