Tried by setting full 8.5x11 margin in set-up, and by making
background color tiff much larger than page, but still prints-out w/
c.1/4" white margin around all design color.
There isn't a limit on the maximum length of post you can make. Therefore,
you are allowed to write using complete words, and even full sentences.
Now, you have not actually set margins at all. The layout guides are just
that - guides. Guides to help you design your publication. They have no
bearing on what prints at all.
The actual margin limitation is introduced either by your printer or your
printer driver - normally the former. It is likely that your printer cannot
print right to the edge of the page, and no amount of fiddling in Publisher
can change that. The solution is to find a printer that supports full
bleed/borderless printing, or to print to oversized paper and trim down.
