Paper advances by n/216 of an inch (1/216" = 0.118mm).
The range for "n" should be from 0 to 255 (OOhex...FFhex).
This command does not move the carriage to the beginning of the next line nor does
it affect subsequent lines: it can be seen as a means to obtain an immediate fractional
line feed with no carriage return for specific paper positioning purposes. If a perma-
nent fractional line spacing is required, command ESC 3 n should be used (see further
on).

It should be noted that value "zero" in the command sequence is the ASCII code zero.
