Hi,

I tried to do some graphics with the DeskJet Plus printer. First using
Signum2 and printed a small picture. This went terribly slow, inspite the
fact that they claim that this printer is 5 times faster with graphics.
(you must take the word 'slow' seriously). I first thought that this was
caused by Signum2, so I wrote a small C-program that just did send of
300 dotlines of 225 bytes each, using the subroutine Bconout (in Turbo-C)
This to went *very* slow. If I send the output to the screen instead of
the printer the output takes appr. the same time. This gave me the impression
that Bconout together with turbo-C are the speed-limiting problems.

The question is: is there any method (preferrable in C, but assembler will
do as well) that allows one to send of characters faster.

Another question is: What is the time one should expect for printing
graphics of 300 * (225*8) dots on the deskjet, without any compression
of transmitted data?
