-: Decrease (Lighter)
bb: Fine adjustment value for print density
00 to 30 (in units of 1 step)
c: Print mode
0: Reserved
1: Direct thermal

(Omissible. When omitted, settings backed up by the memory are valid.)
2-inch print head width
0: Auto (Divided by 2 or 3)
1: Reserved (When designated, automatic selection of bipartite/tripartite
division is performed.)
2: Divided by 3 (Fixed)
3: Auto1 (Not divided/Divided by 2 or 3)/Print quality oriented
4: Reserved (When designated, tripartite division is performed.)
5: Auto2 (Not divided/Divided by 2 or 3)/Print speed oriented

4: Divided by 6 (Fixed)
Explanation (1) The standard density is finely adjusted to increase or decrease.
(2) When any fine adjustment value for print density out of the above range is set, a
command error occurs.
(3) When designating any value other than “1: Direct thermal” the print mode is
corrected to 1.
(4) The default value of the head output division designation is “3: Auto1 (Not
divided/Divided by 2 or 3)” on the 2-inch print head and “3: Auto1 (Not
divided/Divided by 2, 3 or 6)” on the 4-inch print head.
(5) When “0: Auto” is designated on the 2-inch print head, “Divided by 2” or “Divided by
3” is automatically selected for every line according to the print ratio. The width of
half a dot may not be printed on the line when switching between “Divided by 2”
and “Divided by 3”. Therefore, do not designate “0: Auto” when a serial barcode is
printed.
