Supplementary explanation

  • Use this API at the "beginning of a line." If this API is used elsewhere, it will be ignored.
  • For how to register the NV logo, refer to the Technical Reference Guide of the printer.
  • The page mode does not support multi-gradation printing. Multi-gradation graphics can be printed in the standard mode only.
  • The NV logo specified by this API is printed with the color setting specified by addTextStyle in advance and stored in the buffer.
  • TM-U220 and TM-U220II, TM-U330 use only the key1 parameter, however, you need to set "Printer.PARAM_DEFAULT" as the key2 parameter for those printers since an empty key2 parameter causes an error.
