This question is not easy to answer.
The IBM 1403 printer came in at least 2 versions : a 1000 lpm and a 300 lpm.
However, the effective speed depended on what was being printed, as the
chains could be different. Typically, a chain had more E's then Y's, more
A's then P's, etc.
Interesting, The chain printers that I worked on all had the exact same
number of different characters. Depending on the number of characters in
the character set that was used on that partticular printer they usually
had 2 or 3 COMPLETE character sets. IIRC there were 196 positions per belt
and the characters sets that we normalled used were either 64 char/set or
96 char/set. Burroughs had a number of different character sets available
for the printers but in 2+ years that I worked for them I don't recall ever
seeing any used except those two.

I also recall a numeric-only version, which could do up
Topic came up on a local newsgroup - anyone know what the typical speed of
a
chain printer was/is? I can't find any hard
figures online - all the info
about chain printers seems to just say they were "high speed" and that's
it.
to 2000 lpm, and I've heard about (but never seen)
a Braille version
