I have small dot matrix printing device that I'm trying to control (i.e. print to) with a Parallax Propeller board. (See images below.) It's the printer from this: http://shop.usa.canon.com/shop/en/catalog/calculators/palm-printing-calculators/p23-dhv
Is anyone familiar with how one of these things works? I don't see any chips or other electronics on it, so I assume it's just stepping motor control. It seems like I can get specs on the large silver motor from here: http://www.standardmotor.net/sc_webcat/ecat/product_browse_list.php?lang=1&cat=205 but don't know on the rest.
It would be great if there were some sort of "driver" for this for use from Propeller Spin code, but I realize that most likely doesn't exist. If I could at least find some specifications that would describe what I need to send to it, I'd be happy. (Trying to guess what I need to send to each individual motor to get the right output sounds like a rather difficult way of approaching the problem, was hoping there was some sort of documentation or standardized "protocol" that might exist for the overall unit. Definitely have googled a lot to no avail.)
Just looking for some help to point me in the right direction here. I am familiar with the Propeller chip, software development (my main gig), and basic electronics concepts. Never tried to do motor control before.
