Communication between Arduino and Light Meter

Bronson_alex:
On page 4, it says that you can connect to PC using cable T-A11.

Yeah, exactly. But so far I only got the T-A12 cable, which is the cable for connecting with the printer. They looks almost same from the appearance, but is there any difference between these two cables? Can I use T-A12 cable as a replacement of the T-A11 cable? Many thanks
