Subject: Diablo 630 Printer

Richard, the "stock" 630 is not capable of such behavior as boldface
et al as you describe. There is a word processing enhancement to the
printer firmaware, but I have never lloked into ot for the following
reason: WordStar supports boldface, underscore, etc. on the 630 inn
software rather than hardware. It boldfaces by doing a backspace and
re-printing the character several times, for example. To obtain a
pseudo proportional spacing, WS ver. 3.0 has an undocumented
unsupported command. Try inerting a ^P at the top of the file (by
using ^PP) and you will notice a diffference. This is not truly
proportional since it has nothing to do withthe presence of a ps
printwheel, but the results are not all that bad.
