It's however the default size for most printer drivers, so it's often selected as default when trying to print for the first time.
Huh you'd think Windows EU edition or whatever would be smart enough to default to A4.
Europe doesn’t use letter-sized paper, they use A4. I rather doubt that printer drivers installed on a Norwegian computer default to an unusable paper size.
We use the same printers and printer drivers as everyone else in the world. So it does actually default to Letter, and you usually have to change it upon first install. I guess it all comes down to who wrote the printer driver.
I have news for you - the "PC LOAD LETTER" meme works all around the world. Printers and drivers a generally quite dumb about this, and default to Letter format (and this does not make any sense, obviously).
