EK-TM4C1294XL: Thermal printer interface with TM4C129x?

Part Number: EK-TM4C1294XL

Hello All,

I'am new to thermal printers and i want to know from where can I start learning about the interface of thermal printers with TM4c129x.


I've reached a stage in my project where I'am able to capture the biomedical signal and display the waveform on a screen using graphics library.

Now, I need to take print of biomedical signals like ECG,EEG,EMG etc on thermal paper. Just like medical reports!

Which thermal printer should I select? My size options are either 80mm or 106 mm


I've read a TI document in which they have shown a Seiko thermal printer interface with TM4C123, but that is with a GUI.

Instead of GUI I want to send commands through (Pushbutton) using Graphics library.

    This is not directly of concern for this forum, rather for your project management (or you).

    Instead, the "physical interface" would be more interesting (USB, RS232, Centronics, something proprietary ...).

    Well, that sounds like you want to print graphics. In this case, include the graphics support by the printer into consideration, like PDF or PCL file format support. Generating that within your TM4C MCU can become a gargantuan task by itself ...

    Hello Sumit

    You can start with the TI document for TM4C123 and then start to build the graphics library function to use a touch panel.

    Hi Amit,

    I got a 3inch fujitsu thermal printer YC638-101 along with an Interface card .

    I'am attaching the data sheets of both devices. The interface available in the card is RS232 & TTL.

    Kindly guide me how to start developing the firmware to run the printer.628-638_110105 specifications.pdf

    Hello Sumit

    I would ask you to refer to the following application report

    www.ti.com/.../spma071.pdf

    I am not at all experienced with the use of a thermal printers, so would be more inclined for the forum to pitch in.
