I was intrigued by this project so wrote a bash script for those more comfortable in that environment:
#!/bin/bash
xclip -o -sel clip > /tmp/LastClip
while true ; do
xclip -o -sel clip > /tmp/NewClip
diff -q /tmp/LastClip /tmp/NewClip > /tmp/DiffClip
if [[ -s /tmp/DiffClip ]] ; then
cat /tmp/NewClip # For testing dump to screen instead of printing
cp -a /tmp/NewClip /tmp/LastClip
fi
sleep 1.0
done
It does require Xorg’s xclip package:
sudo apt install xclip
It’s dumping clipboard contents to screen using cat command. If you want hard copy instead replace cat with lp and specify your printer name, orientation and possibly “fit to page” option.
You will see a bit of lag to screen because I choose sleep 1.0 which would be unnoticeable with a printer and still faster than people can highlight text and use Ctrl+C.
If you copy the exact same highlighted text to the clipboard it doesn’t trigger a difference. One letter more or less will trigger a response.
