size of the downloaded image.

are the data for the bit image. This data consists of n1*n2 bytes, from left to right and

from top to bottom, but n1 bytes in each horizontal line (n1*8 dots) and n2 lines. Each bit

defines a dot, 1 corresponds to black. Total number of bytes cannot be bigger than 16 kB.

The command defines a bit image that contains number of dots, defined by n1 and n2. Image is

stored and after the printers is switched off.

The so defined bit image is printed with command GS /

82. Printing a Downloaded Bit Image (logo) (GS /)

Code: [1Dh] + [2Fh] + m

m defines the printing mode and can be:

m Mode Vertical dots Horizontal dots

Normal 203 DPI 203 DPI

Double width 203 DPI 101 DPI

Double height 101 DPI 203 DPI

Double height and double 101 DPI 101 DPI

width

When a download bit image has not been defined, this command is ignored.

A portion of a download bit image exceeding one line length is not printed.

Command ESC @ (initialization of the printer) does not clear downloaded bit image.

83. Starting/Ending macro definitions (GS :)

Code: [1Dh] + [3Ah]

Specifies starting/ending macro definition. Maximum content available for macro definition is

4094 bytes. After the last byte of data, the command is sent once again to define the end.

Even with ESC @ (initialization of the printer) having been executed, defined content is not

cleared. Therefore, it is possible to include ESC @ into the content of macro definition.

Normal printing operation is carried out even while in macro definition.

84. Enable / Disable inverse printing (white on black) (GS

B) Code: [1Dh] + [42h] + n

n is from 0 to 255, but only LSB is

checked: 0 Disable inverse printing

1 Enable inverse

printing Default

value: 0.

85. Read the Real Time Clock (GS C)

Code: [1Dh] + [43h]

The command returns the current value of the RTC as string.

Returned data format (21 bytes):

YY MM DD WW hh mm ss[00h]

YY Year without the century (00-99)

MM Month (01-12)

DD Day (01-31)

1 2 ... 23 24 25 26 27 28 29 30 31 32 33 ... 37 38
