Mageia forum

Hi everyone,
I have an Epson all-in-one printer, set to to work in the home wireless network so that 3 PCs (2 laptops, 1 desktop computer) can share it for their own purposes.

How can I set Mageia to change its default settings so that it prints documents as duplex (2-sided printing)? I tried changing the feature in the Printing application but it reverts to "One-sided": Mageia Menu > Applications > Tools > System Tools > Printing > type in root password > select printer > Printer's Properties > select Job Options from the side menu > Common Options > Sides: choose between "One-sided", "Two-sided (long edge)", "Two-sided (short edge)".
Even the web interface of CUPS shows that the default setting is "One-sided" printing and I don't know how to change it. I'm guessing I might have to resort to Kterminal.
I'm attaching 2 pictures, please have a look at them and let me know what I can do to fix this problem.
Thank you for your time.

You would probably use lpoptions.

There is also lpadmin for other cli printer commands.

Hi,
Thanks for the suggestions, David_Batson. Apparently, Mageia can't see the duplex option of my printer. Can you guide me to set it, please?
Here's what I did in the Terminal with the 2 commands, lpoptions -l and lpadmin:

Code: Select all

[aliquis@localhost ~]$ su --
Password:
[root@localhost aliquis]# pwd
/home/aliquis
[root@localhost aliquis]# lpoptions -l
PageSize/Paper Size: 4X6FULL T4X6FULL 2L T2L 4X7 T4X7 *A4 TA4
Quality/Quality: PMPHOTO_NORMAL PLATINA_NORMAL GLOSSYPHOTO_NORMAL GLOSSYCAST_NORMAL *PLAIN_NORMAL PLAIN_HIGH PMMATT_NORMAL
Ink/Ink: COLOR *MONO
[root@localhost aliquis]# ^C
[root@localhost aliquis]# lpadmin -l
lpadmin: Unknown option "l".
[root@localhost aliquis]# lpadmin -o Duplex=Two-sided(long-edge)
bash: syntax error near unexpected token `('
[root@localhost aliquis]# lpadmin -o Duplex=TWOSIDED_LONGEDGE
lpadmin: Unable to set the printer options:
         You must specify a printer name first.
[root@localhost aliquis]# exit
exit
[aliquis@localhost ~]$

The first error is because you used an ( in a command, that has special meaning for the shell.
The second time you get a normal error message, as you didn't tell it what printer to change.
What you want is probably something like this:

Code: Select all

lpoptions -p printername -o option1=value -o option2=value

But http://tig.csail.mit.edu/wiki/TIG/CUPSP ... on_Options states that duplex is the default AFAIU.
