TLDR: Laser printer, no AC, high humidity.

I live in Singapore, the environment here is hot, humid, pretty much all the time.

I'm lucky to live in a house with a good breeze, so I tend to keep the windows open and all the rooms, and rarely turn air conditioning on. When I do it's only for the room I'm in.

My servers and printer, are in a room with no air conditioning usually, this hasn't been a problem historically. But I just got a brother laser printer, and one of those unpacking it I noticed it had a massive desiccation packet packed inside the printable area.

I wonder if people have had any issues in high humidity environments, with either their electronics, or a laser printer?

When I used to live in an area with a heavy ocean sea breeze, I had electronics that rusted from the inside from the high salt content. So I do wonder.

I have noticed paper I leave in a high humidity environment tends to become less rigid over time.
