Linux printing

General information

The printing system at ETH is known as "PIA", Print service of Informatikdienste for All
General information about PIA provided by Informatikdienste (ID)
Overview of personal print jobs and costs

Available print servers

There are different print servers providing print queues for different geographical locations:

pia01.ethz.ch for ETH center buildings
pia02.ethz.ch for ETH Hönggerberg

Stored credentials (see below) will contain the name of the print server.

Available printers

Printers are named and labelled following the scheme "p-building-floor-room", as for example "p-etf-d-104"
The pull printing queue is named "card-ethz" (Nashuatec printers) or "card-hp" for the newer HP printers. It allows releasing a print job on any printer fitted with a card reader by holding a ETH card to the sensor labelled "ETH CARD".
Printers in buildings ETF, ETL, ETZ and HIA are available from Linux clients managed by ISG D-ITET

Storing credentials for authenticated printing

In order to track usage and manage costs every print job needs to be submitted with personal ETH network credentials. The following process describes storing your credentials for automatic submission with every print job.

Open a console
Enter system-config-printer to open "Print Settings"
Double-click the printer card-ethz or card-hp
In the appearing window "Printer Properties" press the button Print Test Page
Enter your username including the domain d\
Tick the check box labelled Remember password to store your credentials
Confirm the dialog by pressing the button OK
In case of wrong credentials the dialog will simply reappear without warning about the fact
Press Print Test Page again, now the dialog asking for credentials should not reappear

Verifying stored credentials

Open a console
Enter seahorse to open "Passwords and Keys"
Verify any entry similar to the one below in your keyring named "Login"

Setting the default printer

Open a console
Enter system-config-printer to open "Print Settings"
Find the desired printer by entering parts of its name into the Filter field
Double-click the printer you want to set as the default printer
Close the appearing "Printer Properties" window by pressing the button Cancel

Now the "Set As Default" menu entry used below will be available
Right-click the printer you want to set as the default printer
Select the menu entry Set As Default
Check Set as my personal printer and confirm by pressing Ok
The default printer is now marked with a heart

Troubleshooting

I've printed something, but it didn't come out of the printer.

Check your local printer queue. Start system-config-printer in your console and right-click -> View Print Queue on the printer/queue you've selected previously. If your job's hanging here, try right-click -> Release. If the desired jobs isn't listed in the queue, check Papercut for errors regarding your print-job. If you can't find any problem, please contact ISG D-ITET Support <support AT ee DOT ethzDOT ch>.

After sending the print job, the printer flashes a red LED and says: Paper size and type mismatched

The Paper type "Recycled" isn't recognized correctly. Use the type "Plain/Recycled".

I've changed my NETHZ password. How can I change the password in the keyring?

After a change of your NETHZ password, you have to re-enter your password on your next print-out. The safest way to do so is to follow Storing credentials for authenticated printing again.

I've started `system-config-printer` but no printers are available.

This probably means the cups service has crashed and can't recover itself. Restart your computer or contact ISG D-ITET Support <support AT ee DOT ethzDOT ch>.

Printouts out of the firefox PDF preview look different from what I see on the screen

The firefox PDF preview is not compatible with our system. Please download the pdf and print it using a PDF viewer. (e.g evince)

The Application (e.g Firefox) crashes when I try to save the password in the keyring.

Please follow Storing credentials for authenticated printing .

After I filled in the authentication popup, there appears another popup that makes the whole display darker and asks about a password for the Gnome Keyring. My NETHZ password doesn’t work!

Open a console and type the command “seahorse”. A Gnome Keyring management tool appears. Delete the “Login “ keyring in the top left corner and log out of your current session. After another login, the authentication process should work.

Print jobs take very long to process/ print out when printing from Firefox

Please download the file and open it with the native document viewer (evince).

A PDF printed from Google Chrome didn't come out of the printer.

Save the pdf, open it with the native document viewer and print it.

OFFENDING COMMAND: setpagedevice

This error often occurs when the document page size doesn't match the printer's paper size. Try to scale the document to a paper size available in the printer and try again.

-Solution I: First, you can check your local printer queue. Start `system-config-printer` in your console and right-click -> ''View Print Queue'' on the printer/queue you've selected previously. If your job's hanging here, try right-click -> ''Release''. If the desired jobs isn't listed in the queue, check https://www.vppspy.ethz.ch (VPP) or https://www.print.ethz.ch (PIA) for errors regarding your print-job.

+Line 76:
-Solution II: There is another option, why the printing system isn't working properly. If the first printer in your print dialog isn't "card-ethz", you might have set an environment variable called "CUPS_SERVER" on the value "ipp2vpp.ee.ethz.ch". Please check your .bashrc / .profile and delete the corresponding line.
