2.1.2.7 Notes on resetting the printer through the interface
The printer reset is available through the interface nInit signal (pin 31) by changing the DIP
switch setting. (Refer to Table 2.1.5. DIP Switch settings for Printer Reset.)
Table 2.1.5 DIP Switch Setting for Printer Reset
Signal Line DIP Switch Reset Condition
Pin 31 (nInt) DSW 2-8: ON TTL-LOW level input
The printer reset through the nInit signal is only available with the SelectIn(1284-Active) signal
at LOW.
To enable the printer reset, the following signal timing shall be satisfied.
Minimum reset pulse width TR: 50 µ

2.1.2.8 Notes on setting DIP switch 1-8 to ON
1) The printer mechanism stops but does not become busy when: an error has occurred,
printing stops due to a paper-end, or paper is fed using the paper FEED switch.
2) When setting DIP switch 1-8 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 and DLE ENQ 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 and DLE ENQ 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 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 r 1 or GS r 49 after transmitting each line
of data and use the 1KB (512 bytes for the multilingual supporting model)
receive buffer. Transmit one line of data so that the receive buffer does
not become full.
