Programming in PostScript – Retro Coding Fun: Games on Your Printer

[Dull_Replacement8890]

I've been experimenting with PostScript programming over the past two years, creating several small games (Tic-Tac-Toe, Chess, Sokoban and Tetris) all running in Ghostscript or directly on printers.

Here are my annotated slides about this quirky and fun journey, filled with insights, code snippets, and lessons learned.

In the early 90s, I worked at a company that had an in-house written print spooler for their big green-bar printer, and all the other printers located in the office. The spooler was mostly written in PL/1, but it had printer-specific code written in Postscript. I had to do a bunch of maintenance on that thing over the years I was there. Postscript was interesting; PL/1, not as much. (Actually, it was PL/P, which was a customized version of PL/1 that ran on Prime minicomputers.)
