in the last year I am looking for software to communicate bleutooth. I have a robot and I want the control it by using the bleutooth or wireless communication. and thank you.(I am sorry for the language)

You might want to do some research on zigbee and xbee modules. They are wireless modules that run on their own protocol and they're pretty inexpensive. I think $21 USD for the cheapest module.


They have this available on SparkFun but the cards aren't cheap. I dont think many on this site have used bluetooth for their bot due to costs.
The cost and how tricky that can be to get up and running the first time....
what is the softwar . you have used. if you can show me the programme whith you have used to communicate whith your printer robot.
I really think the ideas are nice, the only inconvenient is that I have already dismounted the printer, since now I´m working on a tic tac toe that people can play with my Lego in my house using a webcam.

Still very cool to have a protable bluetooth printer, very inventive!

I can't wait to see your other creations :) 

As Zanthess said, it would be awesome if you made it using legitimate parts (plastic, HDPE, etc.) and mounted it vertically on your wall

Very cool!

I could see this anchored to a wall and able to move both horizontal and vertical. Make it so anyone can connect to it and make it print something.

Would make an interesting mural :)
