Thats a very naive question. Is there a single postscript driver ?

At the risk of doing your homework question, I will answer.

Linux (and most unix ) apps emit postscript to the printer subsystem.

The printer subsystem can then either deliver that to a postscript printer,
or translate it.

So if your device isnt going to handle postscript then you would need to
write a translator to turn the postscript into some other language.

Linux uses ghostscript to translate postscript to other printer languages-
however I think ghostscript de-vectorises. have a look to see how
ghostscript outputs to other vector devices.
