Hi,

I need to use a low cost mini printer mechanism in one of my project. My local market provided me an EPSON Model - 42V printer for about $15(INR Rs.650). It has got 3 daisy wheels for printer. One motor and an encoder strip to provide some positioning and timing signals. (I could figure out this much) Googling for it I did not find any datasheet or application notes. Seems a pretty obsolete one. Following is what I have with me:

Code:
1 - trigger magnet - 
2 - trigger magnet + 
3 - motor + 
4 - motor - 
5 - timing signal T --- 
6 - reset signal R --- 
7 - common for 5,6,8 
8 - Timing sub signal t
Any help or suggestion ( for any other printer aswell ) on how to play with it would be of great help to me. The mentioned printer is widely used in Telephone Call Monitor devices in the local market. I really do not have the scope and time to reverse engineer.
