  I think you are right about the RET. Not sure it would make too much a 
difference anyway. You really want sharp clean edges for the traces and I 
think the RET worked by modifying dot size or dithering. Don't think we'd 
want either of these.

  The HP LJ-II/IIIs are tanks that just keep working (well, after you 
replace the triac in the power supply controller they do).

  I do like that a lot of the parts swap between the II & III. The P series 
never seemed to be as robust, or as easy to repair  (but they were cheap & 
worked pretty good for TT).

  When I worked in Manhattan, I'd see HP LJs being thrown in the garbage 
outside of offices all the time. I usually could not grab the whole printer 
(a little too heavy to easily commute home with), but since I always have 
my trusty screwdriver on me....

   I would crack these babies open quicker then a steamed two pound Maine 
lobster and grab the fuser, hv power block, and any other spare parts I 
could toss in my work bag. Sometimes they would even have a half full toner 
cartridge.

    Figure I'll run out of places to buy toner before I run out of spare parts.
