In the general settings of Plasma, the printer can be configured.
But only in theory, not on my PC.
I need paper-size as “A4” , not as default “letter”.
I changed it about 50 times now, clicked on “Apply” , but when I print something, there is “letter” format configured and I have to change it manually each time.
Is there a way to configure it in the general settings-menu of Plasma, so it will stay as selected ?
Yes, I select “A4” and click on “Apply”, but this doesn’t do anything. Zero effect.
It looks like it has been changed to A4, but when I close and open the settings-menu again, the default is “letter”.
Maybe I should mention the printer-model.
It is an old 'Brother printer-scanner model: brother-dcp165c
There is only 1 AUR-package for this model and I installed it hundreds of times on Arch-based distros.
The scanner-driver is brscan3 and scanning works fine. Printing works fine too - but the default media-size is “letter” and defaults to “letter”, which is my problem here.
Edit: lpoptions command will show some print options.
Edit2: Read up on the whole page about lpoptions. You can specify print options and also create saved options for the printer. I don’t know that much about how this all works but maybe you can look at some of the information and maybe it helps.
