Req: someboboy has controlled a thermal printhead with a processor

It's just amazing to see what they can do with processors these days - They're ubiquitous!

Why think that they can't be used for a printhead?

A long, long time ago, before processors were common place, it was not unusual to build complete circuits out of a mythical technology referred to as TTL. It was amazing, but could be difficult to modify.

I had a mate who spent ages designing and building a digital clock using TTL. He was chuffed to bits.

Until ... I pointed out that a day has 24 hours and not 20.

He was sooooo p***ed off, he threw it in the bin!

I made an Amino Acid synthesizer out of a teletype and TTL in the olden days. Talk about "could be difficult to modify"
Later (when that became economically feasible) I made it minicomputer controlled.
I left the chemical analysis equipment area before micros became abundant, but would guess that todays model is microcontroller driven.
