XON/XOFF transmission timing
When XON/XOFF control is selected, the printer transmits XON or XOFF signals as follows.
Transmission timing differs depending on the DIP SW1-3 setting.
NOTES:
• The XON code is <11>H and the XOFF code is <13>H.
•
In case
3
, XON is not transmitted when the receive buffer is full.
•
In case
6
, XOFF is not transmitted when the receive buffer is full.
•
When the DIP SW 2-1 is set to OFF, XON is not transmitted if the printer is in offline state in case
2
.
Notes on setting DIP switch 2-1 to ON
1. The printer mechanism stops but does not become busy when: an error has occurred, the
cover is open, printing stops due to a paper-end, or paper is fed using the paper
FEED
button.
2. When setting DIP switch 2-1 to ON to enable handshaking with the printer, be sure to check
the printer status using the
GS a
command and the ASB function. In this setting, the default
value of
n
for
GS a
is 2. The printer automatically transmits the printer status, depending on
online/offline changes.
3. When using
DLE EOT
,
DLE ENQ
, and
DLE DC4
be sure that the receive buffer does not
become full.
• When using a host that cannot transmit data when the printer is busy:
If an error has occurred,
DLE EOT
,
DLE ENQ,
and
DLE DC4
cannot be used when the
printer is busy due to a receive buffer-full state.
• When using a host that can transmit data when the printer is busy:
When the receive buffer becomes full while transmitting bit-image data,
DLE EOT
or
DLE ENQ,
and
DLE DC4
used while sending the bit-image data is processed as bit-
image data. The data transmitted when the receive buffer is full may be lost.
• Example: Check the printer status using
GS I
or
GS r
after transmitting each line of data
and use the 4KB receive buffer. Transmit one line of data so that the receive buffer does
not become full.
