print buffer.
• This command has no effect in the print modes (emphasized, double-strike,
underline, character size, or white/black reverse printing), except
forupsidedownprinting mode.
• If the downloaded bit-image to be printed exceeds the printable area, the
excess data is not printed.
• Refer to Figure 3.12.3 for the downloaded bit image development position in
page mode.
• If the printing area width set by GS L and GS W is less than one line in vertical,
the following processing is performed only on the line in question:
① The printing area width is extended to the right up to one line in vertical. In
this case, printing does not exceed the printable area.
② If the printing area width cannot be extended by one line in vertical, the left
margin is reduced to accommodate one line in vertical.

[Details] · 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 printer 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
