TECH: HP7550A plotting

I have scoured the archives of this newsgroup and have still not been
able to get my plotter running, I would be happy to get the demo plot
of winline running but at the best I got part of a W out of the plotter
and then it says buffer overflow, I have tried running it at 300 baud
but it starts and just kind of dies. Does anyone have one of these that
can help me go through the settings??? I am running XP with the demo
version of the winline driver.I will install 98 when I get it running
as Ive read that it has the driver.. any help would be appreciated..

Thanks!!!
