Actually, my favorites are the ones where the tractors are right
on the platen. No jams and no wasted paper. I once had an Epson
MX-150 that jammed something awful. I got rid of that. An example
of the former is the Okidata 120, which I used with my C-64. But
to tell you the truth, I can't stand wasted paper almost as much
as wasted hardware ;)
Most older dot-matrix printers had tractors after the
platten/printhead.
Some of them, like my Sanders units have 2 sets of
tractors, before and
after the platten.
Yes, it does mean that you waste a sheet of paper when you finish
printing something - you have to do an extra formfeed. On the other
hand,
I'm quite sure it saves a lot of paper due to the
reduction in the
number
of paper jams. A lot of 'push' type tractors
seem to be great at
mangling
paper...
