Microsoft word puts the header in front of the file with a ^D between
the header and the file.  The header attempts to install itself as
an "exitserver program".  The first line is something like you gave:

    userdict /msdict known { stop } if

This attempts to flush to the next ^D if the header is already loaded.
The next line is something like:

    serverdict begin 0 exitserver

This turns on exitserver mode.

The problem you are seeing is either than the "stop" goes past the ^D for
some reason, or that the ^D is getting flushed.

A simple fix is to remove the ^D's from the file and comment out both the
above lines.  In this case, the prefix is interpreted each time you send
down a file to be printed.  If you have decent communications with the
printer, the overhead of this is small.
