  • Calling this API causes the printer positioned at "other than the beginning of the line."
    This is also true even if 0 is set to "x."
  • After executing this API, addTextAlign and addTextRotate cannot be used.
  • Setting of this API is also applied to the barcode/2D symbol/raster image/NV logo.
  • The setting of this API is applied to each line (Or to each barcode, 2D symbol, raster image, or NV logo).
    If you want to apply the setting to multiple lines, set this API to each of the lines.
