Thanks Tony for the reply.
I'm using a 350mhz PC, Win98, Corel Draw V8. I draw vector images, and always plot
from print preview. I don't type any coordinates in, just send the image.
I was doing more snooping around the HP manuals, and between them, found this:
HP-GL/2 units of measure
The plotter can use plotter units or user units
"Under default conditions, the unit uses plotter-units"
1 plotter-unit=0.025mm(0.00098inch)
40 plotter-units=1mm
1016 plotter-units=1 inch
3.39 plotter-units=1 dot at 300 DPI
Here is a chart that was with the PS info I posted before:
parameter_______format______range________________________default
length integer 0 to 8388607 plotter-units depends
on media size
width integer 0 to 8388607 plotter-units depends
on media size.
These manuals were scanned and saved in Acrobat reader. Print quality seems good
but maybe there's a decimal I'm not seeing???
1016 into 8388607 is 8256.50... 12 into 8256.5 is 688.
688 feet? I'm missing something here. It did say plotter-units, not user units.
Oh well thanks again.

OK, about '1 thou' for UK engineers. Sounds reasonable (this would be the
reslution that the headware is capable of)
40 plotter-units=3D1mm
1016 plotter-units=3D1 inch
3.39 plotter-units=3D1 dot at 300 DPI
OK so far. That much seems reasonable (based on simple arithmetic)

Well, as the 'format' is given as 'integer' there won't be a decimal
point. An integer, of course, is a whole number.
1016 into 8388607 is 8256.50... 12 into 8256.5 is
688.

units.
Yes, I get that too. Sounds far too large. Maybe that's the limits of the
internal control electronics (that is, the plotter will accept vaules
that large without giving an error), even though they are phyiscially
ridiculous.
Oh well thanks again.
As regards sending the PS command, it's not uncommon for software
packages to start a plot by sending various commands to return the
plotter to the power-on default state and/or set up the values needed by
that program. While this makes a lot of sense for most users (it means,
for example, that if you run one program which sets the plotter up one
way, a second program will not get confused by those settings), it is
going to be a right pain for you. If you managed to send the PS command
in some way, it would be quite likely your graphics program would undo
its effects.
The way I would start to tackle this problem (namely connect a
communications analyser between the PC and the plotter and see just what
is sent at the start of each plot) is not going to be applicable to you,
alas.
