•If the width of the printing area set by GS L and GS W less than the width required by the data sent with the GS / command, the following will be performed on the line in question (but the printing cannot exceed the maximum printable area):
➀ The width of the printing area is extended to the right to accommodate the amount of data.
➁ If ➀ step does not provide sufficient width for the data, the left margin is reduced to accommodate the data.
For each bit of data in normal mode (m=0, 48) and double heigh mode (m=2, 50), the printer prints one dot: for each bit of data in double width mode (m=1, 49) and quadruple mode (m=3, 51), the printer prints two dots.

GS :
[Name] | Start/end macro definition | ||
[Format] | ASCII | GS | : |
| Hex | 1D | 3A |
| Decimal | 29 | 58 |
[Description] | Starts or ends macro definition. |
[Notes] | • Macro definition starts when this command is received during |
| normal operation. Macro definition ends when this command is |
| received during macro definition. |
| • When GS ^ is received during macro definition, the priter ends |
| macro definition and clears the definition. |
| • Macro is not defined when the power is turned on. |
| • The defined contents of the macro are not cleared by ESC @. |
| Therefore, ESC @ can be included in the contents of the macro |
| definition. |
| • If the printer receives GS : again immediately after previously |
| receiving GS : the printer remains in the macro undefined state. |
| • The contents of the macro can be defined up to 2048 bytes. If the |
| macro definition exceed 2048 bytes, excess data is not stored. |
| • While the macro is defined, normal printing is executed. |

GS B n
[Name] | Turn white/black reverse printing mode | |||
[Format] | ASCII | GS | B | n |
| Hex | 1D | 42 | n |
| Decimal | 29 | 66 | n |
[Range] | 0 ≤ n ≤ 255 |

[Description] | Turns on or off white/black reverse printing mode. | |||
• When the LSB of n is 0, white/black reverse mode is turned off.
