I know this doesn't give you much information regarding this problem, but I
can say that with 1.2.2 (hog = 1, printer timeout = 10), printing occurs as
soon as I switch away from the app in question, and back to the shell
program that calls it. This seems to release the DOS TSR that spools the
data to the printer. If I don't do that, printing will not occur no matter
how long I wait. However, if I increase the hog value to 2, I don't need to
switch back to the shell for immediate printing. For now, I'm using hog
value 2, which keeps my CPU up around 86%.
