Re: [avr-chat] ATmega16 to printer interfacing

[Dustin Lang]

Hi,

> Could you help me how to interface ATmega16 to printer directly?

First, read this:
  http://catb.org/~esr/faqs/smart-questions.html

Next, decide which port type you are going to use: parallel (DB-25
"centronics")?  USB?  Serial?  Network?  Let's assume you mean parallel.
Google is your friend.  This page:
  http://www.technick.net/public/code/pinouts.php
under the "Parallel IO", read "Centronics" and "SPP". You will need eight
data bits, as well as a few control and status bits.

Next, what kind of printer?  If it's an old dot-matrix printer, you may be
able to just send it raw ASCII.  If it's a postscript printer, it may
accept raw postscript, or it may require a bit of control protocol on top,
I'm not sure.  There are (many) other printer protocols.

Cheers,
dstn.
