[Ed. After much pleading, Woody convinced me to post this message for
him, which contains binary PostScript code (apparently he was
receiving many many e-requests for the code).  I am personally opposed
to distributing binary code on a public discussion group such as this
one for a variety of reasons.  To its credit, this code was posted to
two other newsgroups, and apparently met with lots of approval there.
Note that anyone choosing to use the code (on a postscript printer)
must do so at their own risk.  Furthermore, I do not wish to set a
precedent here by sending out the binary - this is both a first and a
last time.  In the future any and all binaries will be distributed via
the VIRUS-L/comp.virus archive sites, including CERT/CC's anonymous
FTP facility, cert.sei.cmu.edu.]

WHEW!  After 20 or 30 requests for this code, I guess that I'd better
clarify a thing or 2

Please understand that the reset routine allows you to alter ANY part of
the eeprom, including machine hardware registration parameters, printer
serialnumbers (will handily defeat the old Adobe fonts that were tied
to a particular serial number) if you know the serial number, among
many other things.  For this reason, I had determined that there might be
some liabilty associated with the distribution of this code.  Thus the
rules:
 
Department, or company letterhead, signed by a department head.
The basic reason, is so I have some thing to point to if someone says
"I got it from woody...(after messing up a network printer...)
 
My offer still holds, but here is the more benign version.  Both routines
are specific to 68000 based ADOBE postscript interpreters.  Both routines
depend on a short machine language routine that gets downloaded into the
printer, and establishes a new operator.  The following code
handles this by simply reporting the password.  I post it here, as
grabbed off comp.lang.postscript.  This should suffice for nearly all
needs.  I'd prefer people used this one, rather than the one that I have
simply due to the reduced potential for mis-use....

Here is the piece of code that resets the password in a PostScript printer,
which I've obtained.
I'd like to make a point of clarification. Some people might know that Woody
Baker offered to make copies of his code available to people who wrote in to
him, subject to slightly more onerous conditions than at least one other person
on the net thought correct. I then offered to make this code available,
making an oblique barbed reference to Woody in the process. I have since had
the opportunity to speak to Woody about this, and I would like to emphasize tha
t
Woody's code is more complex and contains more powerful, and dangerous
operators than mine, and considerable potential for harm. Woody's terms
are entirely appropriate and generous considering what he had on offer. I
think I've provided a cleaner and simpler solution but those who need the
additional power of Woody's code can still write to Woody.
This program resets the password to zero, using the standard PostScript
operator setpassword. Woody and I both feel that in this form, the code is
useful to those who have forgotten the laserwriter password and don't feel
apple ought to charge and arm and a leg to correct the problem, and not
particularly dangerous, though of course such things by their nature
can cause harm. Please use with care. I can't guarantee this will work but
it's not likely to blow your laserwriter to bits in the process, at least. It
will most likely fail on clones and won't work with Emerald RIPs.
