When you get ready to plot to the HP plotter, AutoCAD talks to the plotter
and the plotter, with paper already loaded, returns the hard clip limits.
This is the area that the plotter says it can plot within. AutoCAD takes
these limits and, based on the drawing area and the scale, determines if the
drawing will fit. If you know that the drawing really will fit, it's safe to
say yes even when AutoCAD says it won't fit. This usually happens when you
are plotting the display, the drawing is actually longer or wider than the
paper, but the extra area has no entities in it. AutoCAD assumes that you
are plotting the entire display and correctly advises you that it won't all
fit. If you were to window the specific area to be plotted, it would most
likely fit within the limits returned from the plotter.
The problem becomes compounded, however, if you plot to a file and then send
that plot file using a separate program. AutoCAD actually sends the blank
area and then plot ends up being "shifted" when you later send the plot
file, resulting in a drawing that doesn't end up entirely on the paper.
I mention that because there are two possible solutions to your problem with
communications parameters. There are several programs, most notably Fastbaud
from Dickerson Enterprises, that let you change the communications
parameters used to communicate with the plotter. It's designed primarily to
send data at a faster baud rate (as the name implies) but may do what you
want as well. The other possibility is to use a plot spooler. Most spoolers
can communicate using any protocol, so you could match it to your other
programs. But you wouldn't be able to plot direct from AutoCAD unless you
then switched it back.
