	How about just looking at the first few characters of the
file? If they are "%!PS-Adobe" (or possibly just "%!PS" or even "%!"),
possibly preceded by a Ctl-D as emitted by certain brain-dead
applications/drivers. This is the strategy used by Sun's printer
drivers, among others. You also need a flag to lpr to indicate that
the file should be printed as text, *even* if it contains the "%!PS"
magic.

	Normally a "-h" flag (to get rid of the "burst page"...)
