Nick, you touch on, or at least evoke, what I have myself noticed --
although my understanding to date is still at what I'll call an
*early* stage...

No matter what resolution I scan at or work in, the printer makes up its
own "mind" -- and does NOT send me an announcement. My current printer
(about to be augmented by inkjet) is a laser with only 4 mb of memory. I
gather that that's the limiting factor, at least with the laser.

But in any form of printer is there a way to make it reveal what
resolution it's actually printing in?
