· When the DIP SW 2-1 is set to OFF, XON is not transmitted if the printer is in off-line state
in case ②.
2.1.1.5 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
on-line/off-line 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
II
I
or
GS r
after transmitting each line of data
and use the 4K byte receive buffer. Transmit one line of data so that the
receive buffer does not become full.
2.1.1.6 Notes on Resetting the Printer Using the Interface
The printer can be reset using interface pins 6 and 25 by changing the DIP switch setting (refer
to Section 3.3.3, DIP switch 2).
Table 2.1.3 Reset Switching

Pin 6 (DSR) DSW 2-7: ON MARK level input
Pin 25 (INIT) DSW 2-8: ON SPACE or TTL-HIGH level input
To reset the printer, the following requirements must be satisfied.
