function adjusts the automatically set print density.

    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 à10.

    (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.

    3”/sec : +10 step

    6”/sec : +5 step

    10”/sec: +2 step

    examples to set the density in thermal transfer mode to +3, and the density in direct thermal mode to -2.

    20 print #1, esc$; ”ay; -02, 1”; lf$; nul$;
