DESCRIPTION
-STROBE
O
Active low. Indicates valid data is on the data lines.
-AUTOFD
O
Active low. Instructs the printer to automatically insert a line feed for each carriage return.
-SLCTIN
O
Active low. Used to indicate to the printer that it is selected.
INIT
O
Active low. Used to reset the printer
-ACK
I
A low asserted pulse used to indicate that the last character was received.
BUSY
I
A high signal asserted by the printer to indicate that it is busy and cannot take data.
PE
I
A high signal indicated that printer Paper is empty.
SLCT
I
A high signal indicates that printer is online.
-ERROR
I
Asserted low to indicate that some error condition exists.
