It seems like it might be possible, in principle, to get a cheap and
accurate postscript previewer given you already have postscript in a
printer.

Couldn't this be achieved by mucking with the device, page-size and
scaling to matchd a host graphic screen or window, rendering inside the
printer at the reduced resolution, and redefining SHOWPAGE to print
the image back to the host in some innocuous ascii format?

Does anyone have any pointers to it having been done already in some
PD or commercial product, or advice on potential problems (including
why, if its impossible) besides the slowness of serial transmission
speed?
