Hello! Thanks for checking this job posting. PLEASE GO THROUGH THIS ONCE BEFORE RESPONDING.

First of all, you need to answer if ESP32 can handle this operation.

We are looking for converting the normal USB based thermal printer to a wireless printer. We need the ESP32 to show up as a wireless printer on the network to all the mobile devices connected to the network.

Once the user sends some file for printing to this wireless printer, the ESP32 recieves this file and transmits this file to the webserver, where we do some modifications to the file.

The modifications include AI based cropping to keep only the necessary material and creates a new file which this server will send back to the ESP32.

Once the ESP32 recieves this modified file, it will then send a print command of this new file to the USB connected thermal printer.

Please reply with SAMSUI if you read this far.

You need to write a firmware for the ESP32 which can handle the specified operation above.

If you can help design a web server too, I am happy to have it done from you. If not, I will hire someone else to get the server thing done.

Please quote your price for both designs if you can.

Please reply only if you are 100% confident that you can write a firmware which can handle the Wireless printer part and can also send the USB print signals to the thermal printer.

I will design a PCB myself and you just need to write the code for the ESP32.

If you think ESP32 can not work here, we are open to using other MCUs as well. But not processors.

Thanks and regards,
