Digital BW, The Print

There is a mathematical process in effect though, it involves converting the
16bit linear data file to a 8bit log file rather than tossing out "...the 8
least significant bits".

Doug,

There's no magic to converting from 16 bit to 8 bit, you just throw away
the 8 least significant bits. I can't imagine that there would be any
difference whether the driver or PS did this. You'd probably save time
pushing data down to the printer if you converted in PS first.
