[FUNCTION]
*Transmits data of NV (Non-volatile) user memory.
*
m
is set to 0.
*a1
、
a2
、
a3 and a4 specify the stored starting address of the data to (a1+((a3x65536) +
(a4x16777216).
*nL
、
nH set the number of stored data to (nL+(nHx256)) bytes.
[DETAILES]
*NV user memory is the memory area which is used for the stored character font data in
non-volatile memory.
*If the values of the argument (
m
), the stored starting address (a1,a2,a3,a4) and the number of the
stored data (nL, nH) are out of the range, or if [the stored starting address (a1,a2,a3,a4) + the number
of
the
stored
data
(nL,
nH)
≧
1024], this command is ignored and the following data are processed as
normal data.
*When the data is ready to be transmitted, the printer executes the following process.
①
Executes (READY->BUSY). If it is already BUSY, the printer executes nothing.
②
Executes to transmit [ Data +NUL]
③
Executes (BUSY->READY). If it is already BUSY for other cause, the printer
executes
nothing.
*The contents of [ Data +NUL] are as follows.
Header: Hexadecimal = 5FH
Data:
Data of NV user memory ((nL+(nHx256) bytes)
NUL: Hexadecimal = 00H
*When DTR/DSR control is selected, the printer transmits all data continuously after confirming if
the HOST is ready to receive data and sending the first header data. If the HOST is not ready to
receive data, the printer waits until the HOST is ready.
*When XON/XOFF control is selected, the printer transmits all data continuously without
confirming whether the HOST is ready to receive data. The transmitted data must be
continuous except for the XOFF code.
*Data of the stored in the NV user memory can be written by
FS g 1
.
*Any delay may be occurred between received transmission of this command and procession of the
stored data depending on the received buffer status.
[CAUTION]
*After starting to transmit header, the printer transmits all data without confirming whether the
HOST is ready to receive data. Thus, (the capacity of the transmitted data + 2) is required in the
received
buffer.
*During data transmission, the printer ignores real-time command. Also, the printer does not
transmit ASB status during data transmission even when the ASB is enabled. Thus, the user needs to
note that the user cannot confirm changes of the printer status during data transmission.
