I would like to print boards without the zone fills when the respective copper layers are selected. More often than not I want to see the pads but do not want to waste toner for filled zones. Should be an option as one might be interested in printing the zone as filled, e.g. for continuity checks.
I do not see any way to achieve that. Did I miss something? If not I’ll post a feature request in the bug tracker…
I have no printer connected to my PC with KiCad so I have checked only with File-Print-Print Preview. When I unfilled zones they disappeared from Print Preview (KiCad 7.0.11 at Windows 10).
If they disappear from preview and you have them in real print than certainly something is not in order.
What KiCad version?
Edit.
When writing and checking I didn’t noticed that eelik already answered.
