I spent a year drawing the fonts for a new printer, dot by dot, the full IBM character sets, in regular, bold and italic. Yow! It only took me an afternoon to create a lowercase font for the old Versatec plotter; the V- 80 was a good low-cost producer, with terrible hardware design and first-class software. It came with a connect-the-dots font editing utility, but only one uppercase font. Did those IBM character sets include APL fonts? Electronic design trivia: the V-80 power supply used screw-terminal capacitors, fastened directly to a thick (3mm) printed wiring board, which was then wave-soldered (solder over screws). Some diodes were under the capacitor, and when heated (and lifted) in the solder process they melted through the insulation jacket on the electrolytic cans, which shorted completely after some time in the field. Melted metal sprayed at each event... Repairing it, you then had to loosen the screws, with the solder-blobbed heads. |

No, it was an office printer, the Howtek color inkjet of 1986, developed by the Centronics engineers. https://en.wikipedia.org/wiki/Talk%3ASolid_ink During an Army field exercise I designed a simple font in about 2 hours, that displayed in the punched hole patterns of Teletype paper tape. The regular printout appeared to be random garbage that satisfied the requirement to exercise the system somehow. A full, credible Times Roman or Bodoni font isn't nearly so quick or easy. |
