Is the origin supposed to be at the lower-left *exactly*?

I have just undertaken a small treasure hunt into the inner working of
printing latex via these two avenues:

	latex -> dvijep -> LaserJetII 
	latex -> dvi2ps -> Adobe-PS-Cart -> LaserJetII

There is a noticeable difference in page centering using these two
methods.  The problem boils down to the fact that dvi2ps assumes that
the lower-left physical page is *exactly* (0,0), just as you have
said.

The printer seems to think that the lower left of the paper is (0.07
in, 0.07 in) in from the origin.  This comes out to the edge of the
paper being roughly at (5,5) on the initial postscript coordinate
system.  Is there a definitive standard on the exact location of the
origin relative to the lower left of the physical page?

If this is a bug, is there some way to fix it up the offset?
Setmargins seems to have much too coarse a granularity to fix up a 5
pt. offset.  Setmargins claims to have a 16 pixel (0.05 inch, or 3.8
pt.) granularity.  So far, I have simply added a 5 pt. offset to each
axis in dvi2ps, but this still leaves my margins off the page for
normal postscript files.

In case anyone else feels like wasting an otherwise perfectly good
sheet of paper and measuring their PS printer's offset, here is my
ruler hack.
