ESC .

Function:

Print Advanced Raster Graphics

Code ASCII: ESC . m n r

d1 … dn

Code HEX: 0x1B 0x2E m n r

d1 … dn

Range:

0 <= m <= 72

0 <= n <= 72

0 <= r <= 65535

0 <= d1 … dn <= 255

Description: Prints a horizontal raster of graphics data one or multiple times. Horizontal

offset and number of data bytes are variable and specified by parameters.

Value of m: horizontal offset from left margin = 8 x m dots

Value of n: number of data bytes that compose the raster

Value of r: number of times the raster has to be printed = 256 x r

+ r

Notes:

•

Advanced Raster graphics is not available in Page Mode.

ESC 2

Function:

Set line spacing to 1/6 inch

Code ASCII: ESC 2

Code HEX: 0x1B 0x32

Description:

Sets the line spacing to 1/6 inch.

Notes:

• The line spacing can be set independently in standard mode and in page

mode.

• Selected line spacing is effective until ESC 3 is executed, ESC @ is

executed, the printer is reset, or the power is turned off. When

underline mode is turned off, the following data cannot be underlined,

but the thickness is maintained.

• 1/6 inch is equivalent to 4.23 mm, which is equivalent to 34 dots.

• In contrast to this command the default line spacing is about 3.37 mm

(7.52 LPI), which is equivalent to 27 dots.

• When the maximum character height exceeds 27 dots in one line,

printer feeds the paper amount of height of the character when

changing lines in the standard mode.

• The linespacing will be set indipentendly from vertical motion unit (see

GS P).
