Sounds like a dumb question but why do the "They" always
say that you have to print with the emulsion side up,
towards the light source? Is there a technical reason
for this?
The rule that I learned was "shiny side up." It applies to
film, paper and cars.

"They" seem to have gotten it backward. For either
contact or projection printing the emulsion side should face
the printing paper. You _can_ print the other way of you
want to reverse left and right, this is called flopping.
However, when contact printing there will be a noticable
loss of sharpness because the image will be spaced away from
the paper. For projection printing the focus will, of
course, compensate for this but there may more blemishes
visible. Pictures are very often flopped for advertising or
similar uses to get image facing the right way in a layout.
Some think everything should face the center, etc.
