You could try looking at some of the linux printer drivers.

If you're not tied down to the HP deskjet, it might be easy to do this with a
postscript printer.  I'm not sure how postscript is actually loaded into the
printer, but postscript is a very simple language and drawing an xy plot would
be quite simple.  A deskjet isn't going to accept a postscript input though...
