ESC r

Function:

Set current color

Code ASCII: ESC r m

Code HEX: 0x1B 0x72 m

Range:

m = 0, 1, 2

Default: m = 0 (monochrome)

Description: This command will set the current color to the color m for all character data

that may follow this command and all graphics objects (bit images) that

have not been explicitly loaded as two-color.

m Connector pin

monochrome - as the initial value

1 two-color paper – primary color usually

black

2 second color available from two-color

paper

Notes:

• The m values 0 and 1 will not have a distinguishable effect; 0 is the initial

value and provides parameter value consistency with other commands.

• When the monochrome paper type command (0 0) is set, this command

is recognized and retained, but has no effect. The monochrome paper

selection (usually black) controls the output.

• When two-color paper is loaded and the two-color paper type command

set, this command will designate which of the two colors will be used for

everything not specified as having an explicit color parameter(s), such al

color logos, side bars, surround graphics, background watermarks or

color raster graphics. The effect mimics shifting a two-color ribbon in a

printer or typewriter to type the color of the lower half ribbon.

• After a power loss or reset the default value m = 0 is set.

ESC s

Function: Write to Non-Volatile Memory (NVRAM)

Code ASCII:

ESC s n1 n2 k

Code HEX: 0x1B 0x73 n1 n2 k

Range: n1 = 1st Byte

n2 = 2nd Byte

20 ≤ k ≤ 63 (decimal locations)

Description:

Writes the two-byte word, n1 n2, to location k in history EEROM.

Notes:

• This command is ignored!
