On LibreOffice 4.2 (GTK2) and LibreOffice 5.4 (GTK3) when I open the print dialog an AT-SPI2 "object:state-changed:checked" about formatting mark is sent.
This event signify that the "formatting mark" will be printed but it is not the behavior.
Steps to Reproduce:
1. Open the attached python listener
2. Launch LibreOffice
3. Press ctrl+p
AN "object:state-changed:checked" event is emitted by LibreOffice
No "object:state-changed:checked" event should be emitted because the user doesn't activate "formatting marks"
User Profile Reset: No
User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:57.0) Gecko/20100101 Firefox/57.0

I can't reproduce on openSUSE Tumbleweed with LO print dialog.

I forgot to mention if you have formatting mark enabled the issue disappears.
You also need to use the GTK2 or GTK3 front-end and to have accessibility enabled in your DE.
