Description
The command adjusts the line spacing for each rotated print line, where n
i
is the
line number and m
i
is the spacing in dot columns (1/80 inch) from the previous
line.

For the first print line, the distance is calculated from the margin. An n
i
value of
0 is used to terminate the command. Any unspecified spacing will be set to one,
which allows data to be accurately positioned on an inserted form. These values
will be used as a template for all subsequently rotated print. On power up, all
spacing is preset to 1/80 inch (n = 1, eight lines per inch) for all lines. The
command is only effective in 90° and 270° rotation modes. The command
remains in effect until a new table is received or until the printer is power cycled.
An [ESC] u <0> will have the effect of setting all lines to 1. The table can be
overridden by [LF] or [ESC] J <n> commands in the rotated print data.
The value of m can be from 1 to 127; n can be from 1 to 22.
Table 13 on page 42 specifies the line spacing for the command.
