		7 x   9  sq inch print area
         x    300 x 300  dots per sq inch
         x         10/8  bits per serial interface byte
         /         9600  bits per second	(19200 baud)
         /           60  seconds per minute

                     12  minutes per page	(6 minutes per page)

If the Macintosh is digitizing the whole page, it will take 12 - 18 mintues
just to squirt it out over 9600 baud line.  (18 for a full 8.5 x 11 inch area)
At 19.2 k baud it will take 6 minutes. 

This is why the drivers had better take advantage of the DeskJet's data
compression protocal.
