Since you seem to want to develop the driver on your own as I find from the email you sent me you are going to have to show here how you have begun the project and gotten started.

For anyone to even attempt to try to give you any help you have to put in a little effort at providing a lot more information. As a bare minimum to even get started you are going to have to....

1) Tell us the nature of your thermal printer mechanism. Provide manufacturer name, model number and interface manual. If this information is available on a web site then just post the URL of the loacation.

2) We would need to know how you have the printer mechanism connected to the microcontroller. If it is just straight wiring from the microcontroller to the printer mechanism then you can give this information in a text list format. Otherwise a schematic showing the information in graphics format will be needed .... particularly if there is additional circuitry between the microcontroller and the printer mechanism.

3) We would also need to know in general what other activities you intend for the microcontroller to be performing. The design of a driver may depend upon the other uses of interrupts and SFRs on the controller.

4) Tell us about the information you were able to find using Google and whether that was able to allow you to get started.

If you indeed want to do this project then get started! Please do not expect a cookie cutter solution that is to fall from the sky into your lap for free!
