Once upon a time there were printers that had vertical tabs, most
widespreadly the workhorse IBM 1403 series which used a small loop of
punched paper tape to specify "stops" for up to 12 IIRC channels, in
much the same fashion as typewriters and now word processor programs
allow you to set horizontal tab stops; by convention channel 1 was
top-of-form only, but others might be site or application dependent.
Many other manufacturers either used a compatible scheme, or an
incompatible but claimed better one. After about 1980 these started
falling out of fashion and I don't think I've seen any since 1990.

You might still find some dusty-deck Fortran that uses (used) these by
outputting carriage-control characters in column 1 other than space
and plus and '1', and maybe some COBOL although COBOL that needed
extensive page formatting would probably better use (have used) the
report-generator features instead of explicit code.
