GS Q

Set horizontal printing position for the bar code

GS k

Print the bar code(s)

ESC X

Magnify characters

GS h

Select bar code’s height

GS w

Select bar code’s width

GS B

To allow/ban white reverse printing mode

ESC l

To set the printing position

This chapter describes the commands of controlling the printer to print. Format

specification is as follows:

【

COMMAND

】

【

parameter

】

【

COMMAND

】

is the command, and consists of the escape character and command

characters. But a small number of single-byte commands don’t have the escape character.

【

parameter

】

is the

parameter

, which is in italics. And the

parameter

s are not numeric

characters, but the value of the character.

All the examples in this chapter are compiled in C language. The ‘

SendDataToPrinter

’ function

is virtual function. And require developers to write according to the actual situation of the

mainframe.

This function is defined as follows:

SendDataToPrinter(unsigned char *buffer, unsigned int len)

Illustration: send the data to the printer

Unsigned char *buf

Print data command

Unsigned int len

Data length. Unit: byte.

3.2 Command Details

ESC

Decimal:

27 64

Hex:

1B 40

[Explanation]

Clear the data in the print buffer, and reset the printing parameters to the
