Need to upgrade a Dot Matrix Printer

Good day, I can help to modify the PCB from an app via Bluetooth in a quality and timely manner. Please share me more details about this project and would be able to best fit for you. I would like to have a thorough discussion on this project as there are certain suggestions from my side After dedicating more than 30 years to the electronics design and development, I am passionate in designing the best products Technology wise I have worked on all the latest technologies like GSM, 5G, Lora, USB, Bluetooth etc. And have worked on more than 20 design tools for designing and simulation purpose Some of the generic queries from my side are: 1. What is the application of this product? 2. What will be the ambient temperature of this product? 3. What are the mechanical constraints to be taken care of? If you are someone who wants to benefit from my experience just message me Hi and I shall be there for you Regards Hari Mohan Engineering for one is magic for others
