1 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.
2 to 9 DATA 1 to DATA 8 Input DATA1=LSB DATA8=MSB
Positive logic code
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.
