Oh yeah, because it was a MSDOS (or unix) program, it had a lot of printer drivers built it, the OS not providing those. I remember working for the Government and having to use carbon paper in the 1990s, which meant using the "daisy wheel" printer[1]. Somehow I selected the wrong printer, and every line printed backwards. Strange times. I don't think this sixel graphics would have printed..

Almost any printer supported PostScript and a parallel port. On Unix you could cat a PS file (supported since groff) to the parallel port at /dev and you were done. Today you can do similar hacks with netcat, the printing port and PDF files.

  Very few non-Apple printers spoke Postscript, certainly at the beginning of the laser printer era. It was an extra cost option available for some printers, which was only bought by people using Apple or the few Unix freaks. And presumably Don Lancaster.
