I distinctly recall the ASR33 printing exactly two

the print head is in motion, if a CR is issued while the print head is
at the right margin. The ASR33 had a very fast and forceful print
head return mechanism--you definitely didn't want to get your fingers
in the way! In my programs that sent data to an ASR33, I always
followed CR with two non-printing characters (typically LF/NUL) and I
never had a problem with characters printing during the print head
return.
Well, I may have exaggerated the time a CR takes slightly, in fact
thinking of 5 or 6 perhaps I was remembering my other teleprinter: a 50
baud Creed 7B which I no longer have. I'm still sure it's normally more
than two character times. Yes, I know about keeping fingers away - and
how to adjust various parts of an ASR33, and I have the tech manuals.
I'm sitting next to a working ASR33 right now.
