What you want is a "watermark." This little postscript snippet prints CONFIDENTIAL diagonally across the page:

/wp$y 792 def
/wp$x 612 def
%-------Customize Here-------
/font /Helvetica-Bold def
/pointsize 96 def
/text1 (CONFIDENTIAL) def
%-------End Customization----
/center {dup stringwidth pop
2 div neg 0 rmoveto} def
wp$x 2 div wp$y 2 div pointsize 2 div sub moveto
.85 setgray
font findfont pointsize scalefont setfont
45 rotate
0 0 text1 center ashow
Merge something like this (a exercise left to someone else) with the postscript sent to Hylafax.
