· Bits 0 and 1: Identified character fonts.
À Read data is transmitted after being converted to ASCII codes.
Á NUL = 00H (0)
· When DTR/DSR control is selected, the printer transmits data consecutively after
confirming whether the host computer is ready to receive data (which is just before
transmitting the header). When 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 consecutively
without confirming whether the host computer is ready to receive data. The data
transmission must be consecutive, except for the XOFF code.
· The printer does not process commands during data transmission.
· The printer ignores real-time commands during data transmission.
· Even if the ASB function is selected, the ASB status is not sent during data
transmission. Also, ASB status detection processing is not executed during data
transmission.
· If the printer status (such as on-line/off-line) changes (except for receive buffer- full),
the required processing (XON/XOFF transmission and DTR control) is executed after
data transmission.
· Since the data and header after reading are required when retransmission is required
by FS b, save them until the next FS a 0 is executed, ESC @ is executed, the printer is
reset, or the power is turned off.
· When reading ends correctly, the printer transmits [header ~ NUL] to the host computer
but does not eject the check.
· When reading ends abnormally, the printer transmits [header ~ NUL] to the host
computer, ejects the check, and then selects the default paper type for ESC c 0. At
this time, the MICR function ends. (Bit 2 becomes 1, and the MICR function is not
selected.)
· When bit 4 is Off (rereading is possible) and FS a 0, FS a 1, FS a 2, or FS b is
received, the printer starts processing of each command.
· When bit 4 is Off (rereading is possible) and character codes other than FS a 0, FS a 1,
FS a 2, or FS b (except for codes corresponding to read-time commands) are
received, the printer ejects the check paper and selects the default paper type for
ESC c 0. At this time, the ASB function ends. (Bit 4 becomes On (rereading is
impossible) and bit 2 becomes On (the MICR function is not selected)).
EPSON
· Bit 4 becomes On (rereading is impossible) in the following cases:
a. Bit 5 is On (abnormal end).
b. Ejection of the current check paper is required to execute re-reading.
c. The number of re-reads reaches the maximum. (The maximum depends on
the reader model.)
d. The MICR function is unselected.
· When bit 5 is On (abnormal end), bit 4 is On (rereading is impossible). Either bit
Off or On has no meaning.
