Early in my career, I worked at a newspaper. Pages were laid out by literally cutting pieces of paper and gluing them (with semi-adhesive wax) onto big sheets of paper. Sometimes on a backlit table, so you could see what the camera would see. Then it was shot with a huge camera. The remainder of the process was messy and entirely mechanical.

“Desktop publishing” changed ALL of that.

And now, we just call it “print.”

Postscript’s contribution to this transformation can hardly be overstated. To have a language for describing a printed page that could be exchanged between all the disparate systems of the 90s, …it was a revolution.
