I found that command in xfce community to make screenshot with print key without pop up window, I remember person here asked in topic about that function in zorin lite, i want to replay there, but the thread is closed.
that command was that:
sh -c 'xfce4-screenshooter -w -s ~/Desktop/Screenshot_$(date +"%Y-%m-%d_%H-%M-%S")'
u can change to another default path.
I went to keyboard app, and related it to print key.
I found that command in that discussion:
ANNOUNCE: xfce4-screenshooter 1.9.11 released / Announcements / Xfce Forums
