A fried who is a LaserWriter hacker asked if there were more tuneup
adjustments one could make to the LaserWriter than just origin positioning.

Specifically, is it possible to adjust the vertical and horizontal
resolutions to get more accuracy?

He asked for a 10cm by 10cm square, and on the "short" paper dimension it
was quite close, but on the long dimension it was .7mm short. It has
remained pretty consistent over about 1000 pages.

Is there a knob to turn inside the beast, or is the only way to send down
some form of translation matrix, which suffers roundoff, etc???????????bc
