Side Effects

A temporary file 'header.lis' is written to the current directory when
using the hardcopy feature. This file is deleted after it is printed.
For this feature to work, your current directly must be writeable. Also,
if you happen to have a file with the same name in this directory it
will get overwritten and deleted.
