6:Do not perform data transfer by ignoring the -ACKNLG signal or BUSY signal. (Data transfer to this printer must be executed by checking the level of the -ACKNLG signal or when the BUSY signal is “LOW”.)

7:Assign appropriate character codes to DATA0 ~ 7 of the interface connector (“1” for open to GND and “0” for short to GND) and connect the BUSY signal line and the - STROBE signal line. Then without using any external equipment, you can conduct printing test of the printer including the interface circuit
