I would like to send a POST request to a thermal printer, but everything sucks so far... Does anyone have any suggestions on which one is the best one?

And also any libraries that would be helpful. Thanks so much guys!

I'm considering these:

* http://www.adafruit.com/products/600

* http://littleprinter.com/

* a standard Star/Epson printer (I don't want to use these because it's costly and I'm a startup)

Thanks again !!!
