Description
1
STROBE
Input
A synchronized signal to read DATA 1 to DATA 8,
Low active pulse is needed.
2 - 9
DATA 1 - DATA 8
Input
In the data input of 8 bits parallel, DATA 1 is LSB (lease
significant bit) and DATA 8 is MSB (most significant bit).
10
ACK
Output
A low active pulse signal indicating receive data intake.
11
BUSY
Output
A high active signal indicating the printer is impossible to
receive any data.
12
PE
Output
A high active signal indicating there is no label.
13
SELECT
Output
A high active signal indicating the printer is possible to receive
data.
