Select or cancel macro definition

Chapter 5: Programming commands 113

Formulas

The distance from the current position is set to (nL + nH × 256) × vertical or horizontal motion unit] inches. The amount of movement is calculated only for the paper roll.

When pitch n is specified to the movement downward: nL + nH × 256 = n

When pitch n is specified to the movement upward (the negative direction), use the complement of 65536.

When pitch n is specified to the movement upward: nL + nH × 256 – 65536 – N

Exceptions

This command is used only in page mode, otherwise it is ignored.

Any setting that exceeds the specified printing area is ignored.

Macros

These commands are used to select and perform a user-defined sequence of printer operations.

ASCII	GS :
Hexadecimal	1D 3A
Decimal	29 58

Starts or ends macro definition. Macro definition begins when this command is received during normal operation and ends when this command is received during macro definition. The macro definition is cleared, during definition of the macro when the execute macro (1D 5E) command is received.

Normal printing occurs while the macro is defined. When the power is turned on the macro is not defined.

The defined contents of the macro are not cleared by the initialize printer (1B 40), thus, the initialize printer (1B 40) command may be used as part of the macro definition.

If the printer receives a second select or cancel macro definition (1D 3A) command immediately after previously receiving a select or cancel macro definition (1D 3A) the printer remains in the macro undefined state.

Formulas

The contents of the macro can be defined up to 2048 bytes.

Exceptions

If the macro definition exceeds 2048 bytes, excess data is not stored.

Execute macro

ASCII	GS ^ r t m
Hexadecimal	1D 5E r t m
Decimal	29 94 r t m
Value of r:	The number of times to execute the macro.
Value of t:	The waiting time for executing the macro.

Executes a macro. After waiting for a specified period the printer waits for the paper feed button to be pressed. After the button is pressed, the printer executes the macro once. The printer repeats this operation the number of specified times.

When the macro is executed by pressing the paper feed button (m = 1), paper cannot be fed by using the paper feed button.
