Laser printers have cancerous particles on it that fly into the air. A little detail when you have it in your house.

I thought about using the same enclosure with carbon filters that I use with my 3D printers but it is a lot of work.

Carbon filters are made from wood, very different from the degenerated aromatic rings of toner.

Also color printing with laser is extremely expensive, way more than color ink tanks with drainage so your printers last a long time.
