EXECUTING + SETTING
[Name] Edit NV user memory
[Printers not featuring this command] TM-T88IV, TM-U230
[Description] Edits the data in the NV user memory.
• Function code fn specifies the function.
• pL, pH specifies (pL + pH × 256) as the number of bytes after pH (m, fn, b, [c1 c2], and [d1...dk]).
• The other parameters are explained under each of the functions.
[Notes]
■ The command function is defined by the function code (fn). The command operation differs, depending
on the function.
■ The NV user memory area is especially provided for storing character data in the non-volatile memory built
into the printer.
■ The NV user memory data configuration is as follows: key code + data + terminator. This unit is called a
record.
• A record is one data processing unit in the NV user memory. It is controlled by a key code.
• The key code is a 2-byte ID code used to identify records and is created with parameters c1, c2 in the
command (Character codes: Hexadecimal = 20H – 7EH/Decimal = 32 – 126.)
