I don't think so.  Jetscript holds the interpreter on disk, and requires
it to be downloaded to the controller board.  Since there is no information
available as to the format required, and as to the port addresses and what
type of port, it is going to be difficult to do this under anything other
than MS-DOS.  There is a loader with the Jetscript board that runs under
DOS.  At anyrate, once you have managed to send the interpreter to the
jetscript board, then you have another problem.  The driver for the board
installs a virtual printer device on the pc.  It is a device handler that
behaves like lpt3.  If you print (using DOS) to lpt3 you get Postscrpt,
if you print to lpt1 you get hp.  There is some magic going on within the
driver code.

The long and the short of it, is that Jetscript is MS-DOS specific.
If you are trying to use it on unix you are basicaly out of luck.
