[Description]
ASCII GS ( L pL pH fn m
Hex 1D 28 4C pL pH fn m
Decimal 29 40 76 pL pH fn m
(pL + pH x 256) = 2 (pL=2, pH=0)

▪ Transmits the total capacity of the NV bit-image memory (number of
bytes in the memory area).
Hexadecimal Decimal Amount of Data
Header 37H 55 1 byte
Flag 30H 48 1 byte
Data 30H - 39H 48 - 57 1 - 8 bytes
NUL 00H 0 1 byte
▪ The total capacity data is converted to character codes corresponding to
decimal data, then transmitted from the MSB.
▪ The data length is variable.
▪ The total capacity of the UV user memory is selectable as any one of [0, 64K,
128K, 192K, 256K, 320K, 384K] bytes with GS ( E . The default value is 384 KB.

▪ Prints the buffered graphics which is stored by the process of Function 112.
▪ Feeds paper by the amount corresponding to the number of dots in the y
direction of the buffered graphics.
<Function 51> GS ( L pL pH m fn (fn=3, 51)

▪ Transmits the number of bytes of remaining memory (unused area) in the
NV user memory.
Hexadecimal Decimal Amount of Data
Header 37H 55 1 byte
Flag 31H 49 1 byte
Data 30H - 39H 48 - 57 1 - 8 bytes
NUL 00H 0 1 byte
▪ The number of bytes of remaining memory is converted to character
codes corresponding to decimal data, then transmitted from the MSB.
▪ The data length is variable.

<Function 64> GS ( L pL pH m fn d1 d2 (fn=64)
[Format]
[Range]
[Description]
ASCII GS ( L pL pH m fn d1 d2
Hex 1D 28 4C pL pH m fn d1 d2
Decimal 29 40 76 pL pH m fn d1 d2
(pL + pH x 256) = 4 (pL=4, pH=0)

d1=75, d2=67
▪ Transmits the defined NV graphics key code list.
- When the key code is present :
Hexadecimal Decimal Amount of Data
Header 37H 55 1 byte
Flag 72H 114 1 byte
Status 40H or 41H 64 or 65 1 byte
Data 30H - 39H 48 - 57 2 - 80 bytes
NUL 00H 0 1 byte
- When the key code is not present :
Hexadecimal Decimal Amount of Data
Header 37H 55 1 byte
Flag 72H 114 1 byte
Status 40H 64 1 byte
NUL 00H 0 1 byte
▪ If the number of the key code exceed 40, the key code is transmitted dividing up to 40.
- The status if the continuous transmission data block is present is 41H.
- The status if the continuous transmission data block is not present is 40H.
▪ After the [Header-NULL] is transmitted, the printer receives a response from the host;
then it performs the process defined by the response. (See the tables below.)
- When the status (existence of the next data block) is Hexadecimal =
41H / Decimal = 65
Response
ASCII Decimal
Process performed
ACK 6 Transmits the next data.
NAK 21 Transmits the previous data again.
CAN 24 Ends the process.
- When the status (for the last data block) is Hexadecimal = 40H /
Decimal = 64
Response
ASCII Decimal
Process performed
ACK 6 Ends the process.
NAK 21 Transmits the previous data again.
CAN 24 Cancels the process.
