“More than half of the websites in the study accepted passwords with six characters or less, with 75% failing to require the recommended eight-character minimum. Around 12% of had no length requirements, and 30% did not support spaces or special characters.”
My HP printer had a hard limit of 16 characters. My password manager generated 20 characters. The login form had no issue accepting 20 characters, which were of course wrong.
Just another reason to not buy HP I guess
