format [esc] ay; abb, c [lf] [nul]
term a: indicates whether to increase or decrease the density.
+: increase (darker)
- : decrease (lighter)
bb: print density fine adjustment value
00 to 10 (in units of 1 step)
c: indicates the mode for fine adjustment, thermal transfer or direct thermal.
0 : thermal transfer
1 : direct thermal
explanation (1) if the print density fine adjustment value has been set in system mode (key
operation on the printer), the fine adjustment value will be the sum of the fine
adjustment by this command and the fine adjustment in system mode. the
respective max. fine adjustment values each are ±10.
(2) the fine adjustment values in thermal transfer mode and direct thermal mode can
be set independently.
(3) the print density fine adjust command is protected in memory (protected even if
the power is turned off).
(4) the fine adjustment value for both fine adjust command and system mode fine
adjustment is 00 at shipment from the factory.
(5) the max. value for each print speed is as follows. when the value exceeds the
maximum, it is automatically corrected to the max. value, and then the printer
prints.
examples to set the density in thermal transfer mode to +3, and the density in direct thermal mode
to -2.
