ESC J n
One line feed of n/180" (for graphics)
n = 1 - 255
Prints the buffer and feeds the paper line feed.If the parameter AGM : NO has been
selected in the SETUP , the paper line feed by n/216"; If the parameter AGM : YES has
been selected in the SETUP , the paper line feed by n/180".
It also executes a carriage return, if the parameter LF + CR : YES has been selected in
the SETUP.
The value of n must be a multiple of 3 (minimum line feed). In 8-needle graphic printing,
the value 24/216" ensures that the lines meet perfectly.
ESC * m n1 n2 AGM
Select Alternate Graphics Mode (AGM)
Allows the selection of 8 or 24-needle graphic mode when AGM: YES has been selected
during SETUP.
Parameter m defines the type of graphic printing resolution according to the following
table:
m Horizontal Resolution

Parameters n1 and n2 give the amount of graphic data plus 1 (calculations as for other
BIM commands).
Normal and high resolution graphics modes (8 and 24 needles respectively) have the
same corresponding bit/needle relationships as those described for the standard graphics
mode (see previous section).
The vertical dot density is 1/180 in.
