I tried to make a high-speed bus between a pair of computers using the parallel port once. But I couldn't get any appreciable bandwidth out of it. Turns out the hardware I was using (CTOS/BTOS workstation) had a capacitor on a critical line. To reduce noise the hardware guy said. But it severely limited the maximum transfer rate. On the widest connector available at the time! Printers don't need to go that fast, he said. Anyway it still seems like a lost opportunity, years later.
