So I've installed the printer Samsung ML-1210 (connected to the LPT port), and it worked fine. Next, I reboot the computer and when I try to print I get the message:

"Stopped - Unable to open device file: Permission denied"

So I re-install the printer, works fine, and next time I start the computer again I get the above message.

It's not a printer issue, as I have a double-boot machine, when I boot into Windows7, the printer works fine. Also, I have another printer (an HP) connected to the USB port, and that works fine (under both Windows7 & Mageia3). I suspect it has somehting to do with permissions. Any ideas on how I can fix this permanently?

Thanks.

Yep, you need to change the permissions of the lpt device that is used for the printer.
Please show the output as normal user of

Code: Select all

ls -al /dev/lp*
id

It's probably enough when you add your user to the lp group via drakuser: http://doc.mageia.org/mcc/4/en/content/userdrake.html
Right-click your user -> Edit -> Groups tab and tick the lp group. OK, then logout and login again.
Does it work now?

Thanks for replying. I am already a member of the lp group, as seen in drakeuser.

The output of ls -al /dev/lp* is

Code: Select all

crw-rw---- 1 root lp 6, 0 May 18 10:43 /dev/lp0
crw-rw---- 1 root lp 6, 1 May 18 10:43 /dev/lp1
crw-rw---- 1 root lp 6, 2 May 18 10:43 /dev/lp2
crw-rw---- 1 root lp 6, 3 May 18 10:43 /dev/lp3

The output of id is

Code: Select all

uid=500(josea) gid=4(adm) groups=4(adm),0(root),3(sys),7(lp),482(scanner),500(josea)

Already a member of the lp group; logged out, logged back in; still does not work.
