• If they deviate from the conditions of the values set in m (Bit Image mode), n1 and
subsequent data are processed as ordinary character data.
Input Data Format
(15) Specifying a bit image (ESC * m n1 n2 D1~Dn)
Code: [1B] h + [2A] h + m + n1 + n2 + Dn
* (m = Bit Image Mode (See the following table.)
(0 ≤ n1 ≤ FF)
(0 ≤ n2 ≤ 03) Data are expressed in Hex code.
Data are printed in a bit image in accordance with the Bit Image mode specified by m.
• The number of dots printed in the horizontal direction is divided by 256, with n2
being the product and n1 the remainder.
• The total number of dots printed as the bit image is n1 + (256 x n2).
• If bit image data which exceed the space of one line are input, the portion of data
that runs over the end is dropped.
• Bit image data (Dn) are specified by “1” in printed bits and by "0" in nonprinted
bits.
• The Bit Image mode is as shown in the following table.
