	If I got it right, what you want to do is make the ehandler
	non-resident, i.e. one that does not stay in printer memory
	after your job is finished. You could do this by simply 
	commenting a few lines (5 to 11 in my version):
	
	%!
	% lib/ehandler.ps -- Downloaded Error Break-page handler
	% Copyright (c) 1984 Adobe Systems, Inc. All Rights Reserved.
	% assumes serverloop password is the default one
%	%/$brkpage where
%	%{pop(Error Handler in place - not loaded again\n)print flush stop}
%	%{serverdict begin statusdict begin 0 checkpassword
%	% {(Error Handler downloaded.\n)print flush 0 exitserver}
%	% {(Bad Password on loading error handler!!!\n)print flush}ifelse
%	% end%statusdict
%	%}ifelse
	/$brkpage 64 dict def $brkpage begin
	/prnt
...etc

	Of course, having done this, you must include the file in every
	print job you need it with. But at least there won't be any extra 
	error message pages.  Our printer server does not seem to add an
	EOF character (ctrl-D) at the end of each job, so downloading
	the ehanldler produced lots of pages reporting timeout.
