Detailed parameters of NFC(NDEF) support (omissible)
etp: Encryption Type
・Detailed parameters related to NFC(NDEF) support is available if nfc: is set to 1. In addition, if nfc: is omitted, it will be
processed as 1 is set in NFC(NDEF) support parameters.
・Not available if nfc:is set to 0.
・Cannot be used together with wbs: and blt:.
・The data write will fail if the created data specified by the detailed parameters related to NFC(NDEF) support exceeds the
maximum byte of the targeted IC chip.
Maximum byte: 224 bytes (for both FeliCa Lite and FeliCa Lite-S)
Parameters related to feed control (omissible)
fsw:
Feed without printing
For ndf:5～6, specify the encryption type of the access point to a fixed 4-digit
hexadecimal.
Valid range: 0001～FFFF(refer to "Setting value of the encryption type" table
in 16.10(14443 TypeA<RK>)).
※ Considering the extensibility of the function, only the digit number is
checked instead of its content.
Normally, RFID write print jobs that don't include print data writes but don't
feed label. (Except for cases with tag offset as default)
When 1 is specified for this parameter, even the print jobs that don't include
print data will feed.
When 0 is specified, print jobs that don't include print data will not feed, which
is the same as not specifying fsw:.
Also, printer only writes without feeding or printing when 0 is specified for
print jobs that include print data, which allows write test without having to
waste label.
If don't feed, Short buzzer will sound 2 times when write is successful. Short
buzzer will the sound 6 times when it fails to write.
In addition, if 2 is specified for the item including print data, a write test can be
performed without consuming label as only write is executed without
feed/print.
Valid range：0-2
