if it uses HPGL you can simply copy the file to the port using the dos

yes and no.
you could but i personally don't advise you to do so.
It is not very likely that it can carry a engraving device, it has not
enough power.

but there are two other ways:
one: use pen with resist and plot circuit pattern

two: "scratch and etch", coat the pcb in laquer and scatch away the areas 
you
want etched, maybe with a rotating scribe.

i have tried method one, and given up. It is awfully slow and the 
resolution is
nowhere good enough for me.

I use toner transfer now, which uses a laser printer, and can reliably get 
6,66mil traces.
and it is way faster than even plotting a simple board.

However you can put your plotter to good use, it can be used
to print the component outline on the board.
you simply use pens for OHP.
You can be sure not many boardhouses offer multicolor component outlines 
;-).



You can try if you want, and if you really only want simple boards.
The moving of the paper is no problem, my hp plotter is built a similar way
and you simply put in a sheet of paper and tack the board to it.
i would say you can reach the same detail as with isolation milling, not 
much more.

If you have a laser printer don't waste your time with that plotter...
