Not a myth. When I attempted to find out from Hewlett-Packard what the
protocol was, I was informed (in writing from an Engineering Manager)
that it was a proprietary protocol and that I would have to obtain the
permission of Microsoft before that information would become available.
You see, we wanted to provide a few thousand of these printers with the
CAT-Scanners we produce for the medical industry.
Since our Realtime OS is __NOT__ Windows, there was no way we could
use these new printers.
Therefore, I had to write a Post-Script driver (not hard to do) and
use a Post-Script printer. The Post-Script protocol is not Public
Domain, but anybody can use it with permission.
Cheers,
Dick Johnson
