I recently came across a Linux feature I have never seen before, where pressing the PrntScr button on the keyboard prints a physical piece of paper with the contents of my console.
I really need to find out how to disable this. It is driving me crazy.
I followed a guide on creating a custom keymap, and I tried remapping it to Esc and loading my custom keymap instead, but it didn't seem to work. By disabling, I mean I would preferably like the key to not send any input at all, and ideally I would like to allow CUPS to continue running.
What exactly controls this behavior? And are there any specific man pages I can read about this?
EDIT: A little bit of additional info I should have given: I launch Openbox after logging into a TTY rather than using a DM. I am looking for a solution that would disable printing even if I were on a TTY, since PrntScr prints from a TTY as well.
