Nope, can't do it. Killed cat, got rid of the "device busy" message but
still can't print.

Why are

Actually, setting up wp51 to print to lp0 was troublesome and erratic, maybe
a problem with dosemu. At any rate, I set up wp51 to use a wp51 ps driver
and set the printer output to file ( which you can do in wp51) instead of to
/dev/lp0, that's why cat a.ps > /dev/lp0, not elegant but works if you don't
forget the redirect.
