Digital BW, The Print

Bob: interesting as I always though all Epson desktop drivers
resampled to 360 dpi. I've never been able to discern a difference
between prints I've sent to the printer at 360 dpi and much higher.
But, I'll have to send the exact same print at 360 and then at 720 and
see if I can tell a difference in the way the print looks.
