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.
