I've used many centronics printers, including the C= MPS series, with the standard Amiga parallel port and a standard centronics cable, no problems.
Pin 14 is the autofeed line (output from the computer end) which most printers don't care about.
As it goes to a TTL level input on the printer, it will not cause any damage.
If you disconnect this line (also pin 14 in the 36 way contronics connector) then it should not make a difference either.
