Configure xfce4-screenshooter default saved file name

Question

The default screen shoot app on Lubuntu allows one to configure the file name. Can that be done with xfce4-screenshooter? How?

A default saved file name looks like:

Screenshot_2021-03-25_10-32-42.png

I do not see it in the help:

me@it:~$ xfce4-screenshooter  -h
Usage:
  xfce4-screenshooter [OPTION…]

Help Options:
  -h, --help               Show help options
  --help-all               Show all help options
  --help-gtk               Show GTK+ Options

Application Options:
  -c, --clipboard          Copy the screenshot to the clipboard
  -d, --delay              Delay in seconds before taking the screenshot
  -f, --fullscreen         Take a screenshot of the entire screen
  -m, --mouse              Display the mouse on the screenshot
  -o, --open               Application to open the screenshot
  -r, --region             Select a region to be captured by clicking a point of the screen without releasing the mouse button, dragging your mouse to the other corner of the region, and releasing the mouse button.
  -s, --save               File path or directory where the screenshot will be saved
  -i, --imgur              Host the screenshot on Imgur, a free online image hosting service
  -V, --version            Version information
  -w, --window             Take a screenshot of the active window
  --display=DISPLAY        X display to use

nor in a config file, /home/me/.config/xfce4/xfce4-screenshooter:

app=firefox
last_user=
screenshot_dir=file:/home/cwhii
action=1
delay=0
region=1
show_mouse=1

Answer 1

In your ~/.config/xfce4/xfce4-screenshooter set timestamp to false to disable the timestamp:

echo "timestamp=false" >> ~/.config/xfce4/xfce4-screenshooter

Next add the title parameter to set the file name:

echo "title=filename" >> ~/.config/xfce4/xfce4-screenshooter

Answer 2

Not an answer to the actual question but until it is a feature of xfce4-screenshooter per Artem S. Tashkinov's comment install the Lubuntu app:

sudo apt install screengrab

This answer to "How do I change my keyboard shortcuts in xubuntu?" tells how to change the app invoked by PrtScr key from xfce4-screenshooter to screengrab.
