- Contact Ryle Design at (517)773-0587. They sell a set of .bgi drivers for
- dot matrix and laser printers. There is at least one other vendor of the
- same kind of stuff, but Ryle Design was the cheapest when I looked into it,
- and I couldn't see any shortcomings in their software, support, upgrade
- practices and plans, etc., compared to the more expensive company.

- You draw an image for the printer using exactly the same routine calls
- you do to draw an image on the screen. (It is NOT a stupid screen dump.)
- If you structure your code properly, you can make one run through your
- drawing code to create a screen image, and then repeat the process to
- produce the equivalent image (but with MUCH higher resolution) for your
- printer. I recall that you cannot keep the screen image up while producing
- the printer image. The process of initializing the driver for the printer
- blanks the screen (it's been 18 months since I messed with this stuff).
- This is an artifact of the way Borland did things, not a screwup on the
- part of Ryle Design.
-
- All in all, Ryle Design's package was inexpensive, works great, and they
- were very nice and competent people to talk to.
