Signal Description
1 In Strobe
†
[nStrobe] A negative-going-strobe pulse causes the printer to read and
latch the data on the Data 0 [1] to Data 7 [8] signal lines.
2 In Data 0 [Data 1] These eight signals form one byte of data sent from host
computer to printer. Data 7 [8] is the most significant bit.
3 In Data 1 [Data 2]
4 In Data 2 [Data 3]
5 In Data 3 [Data 4]
6 In Data 4 [Data 5]
7 In Data 5 [Data 6]
8 In Data 6 [Data 7]
9 In Data 7 [Data 8]
