PostScript was the first language I ever used professionally! :P

At the time, I worked for a printing house in Kyiv that specialized in accidental printing (screen printing, flexo-, tampo- etc. i.e. mostly printing on weird curved surfaces, not paper). The triad (full-color) screen printing was all the rage (early-mid 90s). Part of the process of generating the films that were later used to irradiate the polymer layer covering the screen mold was bound to a bootleg Scitex machines IDF used for printing maps. While we had the machines, we didn't have a proper driver that could take a color image, separate it into channels and instruct the machines to produce the films. So, I'd produce PS files from, eg. Photoshop (also bootleg...) and then edit the PS files by hand to match the requirements from the Scitex machines.

I wasn't a programmer by training, and doing all this stuff absolutely felt like magic. Something I will never experience with computers again :'(
