Direction
Input A low active pulse is necessary in synchronized
signals for scanning Data 1 to Data 8.
Input When entering 8 bit parallel Data, Data 1 is the LSB
(least significant bit) and Data 8 is the MSB (most
significant bit)
Output This is the LOW active pulse signal that indicates the
completion of received data scanning.
Output HIGH active signal which indicates that the printer
cannot receive data.
Output HIGH active signal which indicates that the media has
run out.
Output HIGH active signal which indicates that data can be
received.
Input Signal for when using the IEEE1284 standard.
Connects to the Frame Ground
Output The +5V voltage on the printer side.
Connects to the ground for each signal
Input LOW active signal that requests printer initialization.
Output LOW active pulse signal that indicates a printer error.
Input Signal for when using the IEEE1284 standard.
