Description
➊
When the printer receives this code sequence it advances the paper by
n
⁄
180
inches
(24 needle printer) or by
n
⁄
216
inches (9 neadle printer). This sequence does not effect
a CR (reset line pointer).
➋
When the printer receives this code sequence it moves the paper backwards by
n
⁄
180
inches (24 needle printer) or by
n
⁄
216
inches (9 needle printer).
Unlike an ordinary line feed code, code ESC J does not advance the paper to the top of
the next page when the print position enters the perforation area (Perforation-skip operati-
on is not performed). The value specified for n must be in the range of 0 to 255. This code
sequence does not affect the amount by which the paper is advanced by subsequent LF
or VT codes.
