Thermal printer

[jonas2]

Hello

I retrieve a thermal printer on a terminal, I did research and impossible to find a scheme of this model (see photo).

THERMAL PRINTER SEN302620B V003 22/04 PROV 3379

And there is a double wiring for the printer

Certainly going to at least be very difficult if not impossible to get the specs for that. Not to mention that you would have to build a circuit that could feed it a fair amount of current so parts of it could get hot.

I would go the easy route, and buy a serial thermal printer on ebay for about $40. We use a lot of Epson TM-88 M129A serial thermal printers at my work, and they are pretty indestructible. My search on ebay found a few for under $40.

one of my friend bought a pos machine:) there is a printer in it.
and the question is how can we use it?

Thanks for your help:)

I don't really understand what you are trying to do. You showed the print head for the thermal printer, but did you want to try to build your own hardware for the print head, or were you going to try to use it in the POS that your friend has?

If you are thinking of trying to use the print head alone, my advice is to take the easy way out and buy a $40 thermal printer that can accept serial instructions.

If you want to use it inside the POS, then perhaps your best bet is to find out what type of POS machine it is. With that information, you might be able to google the drivers for the type of printer, or see if anyone else is trying to do the same thing. If the hardware is PC based, you might get really lucky, and have

What I ask is:
How can we use pos machine's printer?

We have no problem with pos machine:) just wanna use its printer:)

Thanks:)

Here is some information about a few different print heads. It should help you understand a little more about how to interface to one. Of course, you will need the data sheet for your specific print head. That always seems to be the problem when I buy surplus.

What you are attempting to do is difficult. Kind of seems like the equivalent of programming a PIC chip to be an lcd driver chip, only with the added complication of printing on moving media. But if spending 40 plus hours building something you could buy for less than $40 sounds exciting, you will learn a lot!

Let us know how it goes.

It looks like the manufacturer is still around, so you could ask them about the print head schematic.
