I want to try to fasten the thermal printer to the microcontroller. I don't know which printer to get

Question

Do it yourself

Dear cheaters!

I've been thinking about attaching a thermal or pos printer to my stm32f4discovery for a long time. And do something like a “seismograph” on this: I move the board, and graphs are drawn on the tape in real time.
The question is: which printer to choose?
I settled on this - cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=110942921206 Thankfully
it's cheap.
What do you advise? Is this one worth getting or is there another one better?

Answer 1

Are you happy with the fact that it's on USB?
For DIY, there is also this: sparkfun and adafruit . Rulitsya on TTL Serial .

Answer 2

According to the experience of communicating with thermal transfer printers, I advise you to pay attention to the availability of high-quality documentation on communicating with the printer, and the speed of its printing in an acceptable quality for you. Possible rake: they are very capricious in terms of input data (including temperature and image resolution / number of characters per line, which take a long time to select drearily), and the quality of consumables. Yes, yes, when printing, depending on the resolution and print speed, you need to tell the printer what temperature to give out on the head.

I worked with Sewoo printers, it was outputting graphics, but not from the microcontroller, but via Wifi (the printer had a wifi module), but it doesn’t matter. There is not a lot of documentation for them, but there is no need for a lot of it. I think you need to select a printer with an interface that your MK has, so as not to bother with the conversion of interfaces. The easiest way is probably to find a printer with RS232.
