Description
Synchronization signal that requires low active pulse
to read DATA1 ~ DATA8
Data entry of 8 bits parallel: DATA1 LSB (lowest bit)
Low active pulse signal indicating the completion of
receive data import
High active signal indicating that the printer is not
ready to receive data
High active signal indicating paper shortage
High active signal indicating that the printer is ready
to receive data
Signal for the IEEE1284 standard
Connecting to the chassis ground
+5V voltage on the printer side
Connecting to each signal ground
Low active pulse signal initializing the printer
Low active pulse signal indicating an error in the
printer
Signal for the IEEE1284 standard
DATA8 MSB (highest bit)
