Mostly OT...
To expand on what John wrote, some (mostly older, and typically line)
printers could have vertical tab stops programmed. On some printers
this was actually done via a punched carriage tape (the tape was a
loop, with holes punched where the stops were desired). Those could
be changed for different print jobs. In many cases a skip to the next
vertical tab could happen much faster than advancing individual lines,
so for fast printing, you'd carefully set up your carriage tape (or
electronic equivalent).
With most current printers, that's all pretty irrelevant.
Note that some printers (and display terminals) also allowed you to
set the horizontal tab stops (the now common "every eight" convention,
was not always the, *ahem*, convention).
