nSTROBE
Input
To scan data, make sure that the pulse width of the
strobe pulse is set to more than 1 µs.
The regular status is “High”, however, if it is “Low”, the
data will be scanned in the first transition.

ASCII or JIS7 as well as 8.
10
nACK
Output
A low level pulse signal will be output when data
scanning is complete to inform the host.
11
BUSY
Output
“High” will be maintained when the Reception buffer
has reached full or when an error occurs in the printer,
and “Low” will be output when the printer is ready to
receive.
12
PE
Output
The level will become “High” when labels have run out
and none have been set.
13
SELECT
Output
The signal will be in “High” level when reception is
possible, otherwise it will be “Low” level.
32
nFAULT
Output
The signal will be in “High” level when reception is
possible, otherwise it will be “Low” level.
