My margins keep resetting themselves at 2.67". Why?

[Library Lady]

Often, Word resets my margins, either left or bottom, at 2.67". I am given a
chance to fix them, but even if I do, they revert to 2.67".

It becomes a real problem with a large mail merge print run. Lots of wasted
paper that has to be reprinted.

 

[Suzanne S. Barnhill]

This is a result of a conflict between Word and the HP drivers for certain
LaserJet printers. Various workarounds are said to work, but many users have
reported that new drivers from http://www.hp.com/pond/ljbeta/index.html
solve the problem.
