To Russell:
The first sequence only has one byte following the "*". This is 80 hex
(128 decimal, which is not a numeral). The second has 73 30, which is s
0 (small s nought), decimal 115 48 (perhaps these are the dimensions (in
pixels) of the heading on the page (seems plausible). I will do some
more experiments on this.
If these are HP escape sequences, then they are not PCL 3 or 4.

General Points:
As for suggestions of the possibility of signing a non-disclosure
agreement, forget it; I would rather continue reverse engineering the
codes (Yes, I am aware that this may be illegal, but I payed for the
machine and I intend to make full use of it).

As for my foolishness in buying the printer without research, yes, in
hindsight it may seem that way. However, the special price on offer,
with some bundled software that my wife wanted, made it a very
attractive machine.

I doubt that blacklisting (even if possible) would have any effect.
Let's not have any delusions; Linux users represent a very small part of
the hardware market, both in number of installations, and in dollar
terms; particularly in dollar terms.

I am bowing out of any general discussion of this issue. If anybody
wishes to discuss the technical aspects of this challenge, please email
me personally.
