Return boot sector firmware part number
ASCII
GS NULL
Hexadecimal
1D 00
Decimal
29 0
Returns ACK (Hex 06) + 12 bytes ASCII string describing the flash memory boot sector firmware part number.
Ex : 189–1234567A
Exceptions
Available only in download mode.
Return segment number status of flash memory
ASCII
GS SOH
Hexadecimal
1D 01
Decimal
29 1
Returns the size of the flash used. There may be 16
(1 Meg) or 32 (2 Meg) sectors in flash memory. This command assures that the firmware to be downloaded is the
appropriate size for flash memory. The value returned is the maximum sector number that can be accepted by the
select sector to download (1D 02
nn
) command.
Exceptions
Available only in download mode.
Select flash memory sector to download
ASCII
GS STX
nn
Hexadecimal
1D 02
nn
Decimal

nn
Value of
n:
The flash sector to which the next
download operation applies
Range of
n:
0
Selects the flash sector (
n
) for which the next download operation applies. The values of the possible sector are
restricted, depending upon the flash part type. The printer transmits an ACK if the sector number is acceptable or an
NAK if the sector number is not acceptable. Sector numbers start at 0.
Exceptions
Available only in download mode.
Get firmware CRC
ASCII
GS ACK
Hexadecimal
1D 06
Decimal
29 6
Causes the printer to calculate the CRC for the currently selected sector and transmits the result. This is performed
normally after downloading a sector to verify that the downloaded firmware is correct. The printer also calculates the
CRC for each sector during power up and halts the program if any sector is erroneous.
The printer transmits ACK if the calculated CRC is correct for the selected sector; NAK if the CRC is incorrect or if no
sector is selected.
