Sets line spacing at n/216 in. The valid entries for n are 1 to 255.
n/216 in. line spacing is approximated using 1/144 in. steps. Maximum
local and cumulative error is - 1/216 in.
ESC 3 (n) causes all subsequent line spacing to be set at n/216.
ESC J (n) prints all data in the print buffer, clears the print buffer, then
advances the paper n/216 in., one time only. ESC J does not perform
a carriage return with the linefeed.
Note: n/216 in. line spacing is called "Graphics Line Spacing" by some
manufacturers. Use a line spacing of 24/216 in. for bit-image
graphics using eight bits.
