Network Printers

• Attention: Cups Printing Service is a preliminary service. At the moment the changeover from LPRng to Cups are causing some problems.

• Using cups printing commands you can not specify an option for queues depending on the LPRng printing system.

Overview Cups Printing Options on UNIX

Printing Options are passed to Cups using the -o Option of lp and lpr:

• lpr -o option1=value1 -o option2=value2 [...] file

• lp -o option1=value1 -o option2=value2 [...] file

For more options and additional information see the [http://localhost:631/sum.html "Cups Software User Manual"] (If there is no Cups daemon running on the local machine, this link won't be available)

Frequently Asked Questions

Why changing the printing system?

• LPRng is no longer supported

• Cups is better intergrated in Linux Desktops like KDE and Gnome,in OpenOffice and other applications

• the user can select features like resolution, duplexing, pagesize etc.
• Cups is easier for the administrator. The printer PPD files are used.
• Samba and Cups are working very well together for the Windows Print Service.

Which file formats can Cups process ?

• PostScript, PDF, International Text, TIFF, GIF, PNG, JPEG, SUN−Raster and other graphic formats

• CUPS uses the configuration file /etc/cups/mime.types to define the rules, which are applied to unknown file types in order to get a MIME typization for them.

Which applications support cups features on a UNIX System ?

How can I print simplex on a duplex printer on a UNIX system ?

• use option sides=one-sided

• using lpr: lpr -Pprinter -o sides=one-sided myfile

• using lp: lp -d printer -o sides=one-sided myfile

• if simplex instance exists: lp -d printer/simplex myfile

Why there are not an A3 queue and a transparency queue anymore?

• Now there are only one queue for a printer. The filtering of the print job will be done on the local host, no longer on the print server. The user can specify all possible features via command line option or GUI.
• Lists the printer specific options and their current settings with

  • lpoptions -p printer -l

• examples
  • A3 printing: lp -o pagesize=A3 file.ps
  • transparencies: lpr -o media=Transparency talk.ps

How can I remove a printjob on a UNIX system?

• The problem is that the Cups job on the local system gets a job-id, but on the print server a different one. After finding out the job-id on the print server you can remove it. Use cancel and no longer lprm for removing your print jobs.

How can I change personal printer specific option settings?

• Use lpoptions to save personal option settings in ~/.lpoptions. Example: lpoptions -o pagesize=A3 -p znecad

How can I print multiple Copies of one Printjob with CLI?

• using lp: lp -n number-of-copies file

Copies are not collated by default. Use the -o Collate=True option to get collated copies:

• lp -n number-of-copies -o Collate=True file

How can I change the Layout of the Outputpages when using N-Up printing?

In order to change the borders around each page, use the -o page-border=value option. Supported borders are:

• none: do not draw a border (default)

• double: draw two hairline borders around each page

• double-thick: draw two 1pt borders around each page

• single: draw one hairline border around each page

• single-thick: draw one 1pt border around each page

Example: lp -o number-up=4 -o page-border=double myfile

In order to chooses the layout of the pages on each output page, use the -o number-up-layout=value option. Possible values are:

• lrtb: Left to right, top to bottom (default)

• lrbt: Left to right, bottom to top

• rlbt: Right to left, bottom to top

• rltb: Right to left, top to bottom

• tblr: Top to bottom, left to right

• tbrl: Top to bottom, right to left

• btlr: Bottom to top, left to right

• btrl: Bottom to top, right to left

Understanding the layouts: The default layout is lrtb(Left to right, top to bottom). This means: using a number-up of 4, the first page will be printed on the top-left of the outputpage, the second page will be printed on the top-right, the third page will be printed on the bottem-left and the fourth page on the bottom-right of the outputpage.

Example: lp -o number-up=4 -o number-up-layout=btrl myfile

I'm using psutils (pstops,psnup,psbook). Even though I'm using the option ''sides=two-sided-short-edge'' the output was not arranged in the correct order. What can I do?

• the psutils tools are old and not maintained for 10 years, but there are not a replacement for them.
• With the following command you can bypass the postscript filter

  • lp -o document-format=application/bindshort -dprinter myfile

I'm using psutils (pstops,psnup,psbook). On the Xerox Color Printer I get wrong output with a different font. What can I do?

• the psutils tools caused this problem.
• With the following command you can bypass the postscript filter

  • lp -o document-format=application/bindlong -dprinter myfile

  • or lp -o document-format=application/bindshort -dprinter myfile

Printing from Notebooks

Linux Notebooks

using cups

If you used one of the following methods to make your local cups to communicate with the Server, you can use cups as described above.

with local cups-daemon

If you want your Cupsd to communicate with the server permanently, just add the line Browsepoll zncups.ifh.de to /etc/cups/cupsd.conf and restart the cups-deamon by typing /etc/init.d/cups restart as root. From now on, the cups-daemon will comunicate with zncup everytime cups is started. If you just want cups to communicate with the server for the current session, you can start the cups-polld manualy. Generaly it is located in /usr/lib/cups/daemon/. You can start it by typing /usr/lib/cups/daemon/cups-polld zncups.ifh.de 631 30 631 as root. If you do so, there is no need to restart the local cups-server. By default, the Printer-informations are lost 5 minutes after stopping the cups-polld.

without local cups-daemon

If you have no local cupsd running, just change the Servername directive in /etc/cups/client.conf to zncups.ifh.de

using LPRng

todo

Windows Notebooks

• click "run" in the Startmenu
• type "\\zncups" and press Enter. You rNotebook will connect to the Printserver.
• choose a Printer. doubleclick to add a Printer to your Notebook. The printerdrivers will be downloaded.
• go to "Printers and Faxes" in the Startmenu if you want to change the Printers configuration.
• thats all

Known Problems using Cups

• network trouble or problems on the print server can cause an empty printer setup on the clients
• psutils and cups filter don't work together
