This takes me waaaaaaaay back to when I did my first bit of practical low-level programming. I wrote a little C program that translated PNM bitmaps into the wire format for my dusty 24-pin Epson dot matrix printer. I don't remember the details, but I used it with some plugin system involving Ghostview to print postscript documents from my first Linux system in the early 90s.
