· yL, yH, select the number of data bits ( yL+ yH´256) in the vertical direction for the

bit image.

[Details] · In standard mode, this command is effective only when there is no data in the

print buffer.

· This command has no effect in all print modes (character size, emphasized,

double-strike, upside-down, underline, white/black reverse printing, etc.) for

raster bit image.

· If the printing area width set by GS L and GS W is less than the minimum width,

the printing area is extended to the minimum width only on the line in question.

The minimum width means 1 dot in normal (m=0, 48) and double-height (m=2,

50), 2 dots in double-width (m=1, 49) and quadruple (m=3, 51) modes.

· Data outside the printing area is read in and discarded on a dot-by-dot basis.

· The position at which subsequent characters are to be printed for raster bit

image is specified by HT (Horizontal Tab), ESC $ (Set absolute print position),

ESC \ ( Set relative print position), and GS L (Set left margin ). If the position at

which subsequent characters are to be printed is not a multiple of 8, print speed

may decline.

· The ESC a (Select justification) setting is also effective on raster bit images.

· When this command is received during macro definition, the printer ends macro

definition, and begins performing this command. The definition of this

command should be cleared.

· d indicates the bit-image data. Set time a bit to 1 prints a dot and setting it to 0

does not print a dot.
