Excluding items from the printout does not work

Hello,
Your plugin is great, thanks a lot!

However, I can’t seem to exclude from the printout content the custom button I’ve chosen to lauch the printing.

I put a “my_print_button” ID on it:

<img src="https://projectdmc.org/support/topic/excluding-items-from-the-printout-does-not-work/button.png" id="my_print_button" data-print_target="article" do_not_print="my_print_button" class="printomatic" data-print_target="#print_me_please"></img>

And in the Print-O-Matic settings on WordPress, I specified this:

But this blue button still appears in the printout.

I also tried to replace in the “Do Not Print Elements” field, instead of the id “my_print_button”, the class “printomatic”, but it doesn’t work either.

Can you help me? Thank you very much in advance!
