By sending the following postscript job, it should change the port speed.
Note that this is persistent across power cycles. Note that some
machines have a limited number of programming cycles, since they use
EEPROMs, so you probably don't want to do this at boot time :-)
------------ snip -----------
%
% if your Postscript printer has a supervisor password
% replace the 0 (zero) below with it
%
serverdict begin 0 exitserver
statusdict begin
%
% the first parameter is the port 25 indicating the 25 pin serial port
% and 9 is the 9 pin port
% the second parameter is the serial port speed
% the third parameter is the parity:
% 0 is ignore top bit (7 bit chars)
% 1 is odd parity
% 2 is even parity
% 3 is no parity (8 bit chars)
%
25 115000 3 setsccbatch
------------ snip -----------
Hope this helps.

I think your solution will be to increase the serial port speed on the
LaserWriter from 9600 to some other value. Am quite sure it can be done
(at
least 56k) but don't know how. I'd net surf looking for "Don Lancaster"
as
he has written much over the years on hacking LaserWriters and
Postscript.
