Dear Priya,

As I write these the datasheet is being mailed to you. (My broadband upload speed sucks!).

Darrel I think it is a good idea to have it on your website thus I am again uploading it to rapidshare and posting the link. http://rapidshare.com/files/76897214/Epson_M42-V.pdf
I lost the code (and a lot other) when my 250gb Seagate was fried. I keep backups but do not really have a good incremental backup tool, (no free backup tool that I could locate) so things are really messed up. All I can remember is that I did some filtering on the signals from printer using R-C network followed by a Schmitt trigger. Also I remember that sometimes the count was wrong so instead of printing too fast I was printing then grabbing pulses and printing again. For experimental purposes I used PWM channels for both the motor drive and the solenoid but did not actually use them. Driver used was a ULN2803 with outputs paralleled. (4 for the motor/ 4 for the solenoid)
