Anybody used EPSON M-42V Daisy wheel Printer

[Jerson]

For the sakes of future requesters, I've posted the datasheet on my website on the downloads page.

hello sir,
can u please provide me some information regarding, "interfacing m42v printer with 8051"?
thank you

Tell us what you have done till now to interface the printer. If you run into some trouble with what you have, you can get help. But, you need to have done at least some preliminary work.

Yes Sougata, I have interfaced this printer with 8051

hi. jerson sir,

i am rilesh , a student of B.E> Entc and i wanted to use epson 42
v printer for my project which is similar to something used for
ticketing purpose in bus transport. i want it 4 printing recepts.

i hav got the datasheet of it. thanks to u 4 that. i am using avr
microcontroller and want to interface the printer to it. i just want to
know how the character selection is done and the tips regarding its
programing with microcontroller. i hav got some idea regarding driving motor
and the magnet, but bit counfused regarding selection of charcters.
Some example of code would be a great help.

if u could send me some data regarding this then it would be a great
help! my email id is



thanks once again for datasheets. i could get that only because of
u.bye. hav a nice day!

Hello Rilesh

We are here to help you. However, show us what you have done till now. I'm very sorry, I do not entertain requests for code. If you post what you have, someone here sure will guide you.

hi jerson sir,
i hav got ur reply. thanks for showing the interest in helping me.

as i hav told u earlier i hav got the driver circuit that drives the motor and the permanent magnet. but i am not finding any data on the remaining signals like
1. T
2. rst
3 . common(c)
4. t

if u could send me some data regarding how this signals can be used it will be a great help.

mail me on my id:

Again, if you have done some coding, show it. We can guide you.

As far as the signals you mentioned, RST tells you when the wheels are at 0 position. First character on the wheels. The T (timing) pulses tell you when the wheel has advanced 1 character. This is from memory, I have not consulted the datasheet.

We could discuss your problems here since a forum exists for everyone to benefit. Today, its you who have a problem. Tomorrow, someone else who has the same problem will find the solution right here; whereas with email, the same questions will repeat.
