Considering how complex printers are, I think a lot of them are designed and engineered well but could use a redesign of the user interface. Often settings between the computer and the printer have to match exactly to have a successful print, and it would be nice to tell a printer what your end product is instead of juggling the settings to reach your desired print. Most of my frustrations are from the large laser printers at the office, but our new Ricoh is pretty nice, when there’s a jam it clears the paper into a lower bin for removal.
