if you read the "description of signals" carefully, you should find all you need. It's just a matter of assigning port pins to the proper signals that need to be read/written... (and of course physically interconnect these...)

You then would have to follow procedure as described in paper to present your data to be sent to the printer on the data-lines

don't forget that the printer only understands escape-sequences and
ascii codes...
