I would argue that for the humble serial or parallel port printer, things just worked. Yes, the ribbon needed replacing sometimes, and the tractor feed could snag or jam. But that's all a see-it-and-fix-it situation - zero tools required. These things took raw serial data, a straight dump of ASCII characters on the wire. Nothing to confuse and nothing to get wrong. No wacky software drivers either - just tell the software what hardware port to talk to and you're printing. You got boring text, tabs, spaces, newlines, and zero frills.

For whatever reason, the moment we started to emulate professional printing on a consumer budget was when things started to get hairy.
