CHAPTER 5 CONTROL COMMANDS LIST ESC * [Name] Select bit-image mode [Format] ASCII ESC * m nL nH d1 ... dk Hex 1B 2A m nL nH d1 ... dk Decimal 27 42 m nL nH d1 ... dk [Range] m = 0, 1 0 ≤ nL ≤ 255 0 ≤ nH ≤ 3 0 ≤ d ≤ 255 k = nL + nHx255 [Default] None [Description] Selects a bit-image mode using m for the number of dots specified by (nL + nH x 256) as follows : m Mode Number of bits for vertical data Dot density in horizontal Amount of data ( k) 0 8-dot single-density 8 Single-density nL + nH x 256 1 8-dot double-density 8 Double-density nL + nH x 256 [Notes] Data (d) specifies a bit printed to 1 and not printed to 0. If the bit image data exceeds the number of dots to be printed on a line, the excess data is ignored. The bit-image is not affected by print mode (emphasized, double-strike, underline, character size), except for upside-down printing mode. After printing a bit image, the printer processes normal data. When printing multiple line bit images, selecting unidirectional printing mode with ESC U enables printing patterns in which the top and bottom parts are aligned vertically. This command is used to print a picture or logo. The relationship between the bit image data and the print result is as follows. 8 dot mode (m = 0,1) MSB d1 d2 .... dk LSB 5-16 The modes selectable by m are as follows: - "Vertical" is in the direction of paper feeding and "horizontal" is perpendicular (at right angles) to the direction of paper feeding. - The maximum number of dots for printing depends on a DIP Switch [DSW1-8] setting and paper width. See the description of GS ( E , for details.

When underline mode is turned off, the following data cannot be underlined, but the thickness is maintained. This command and bit 7 of ESC ! turn on and off underline mode in the same way. 5-17
