Hello, I have a strong experience in creating C++/Qt based applications for different platforms. You can refer to my profile for some examples. Also I have an experience with some external devices like a MCC USB-202-OEM board, USB-to-Serial converter, MODBUS protocol, etc. I think you need custom solution in your case. Most probably you can't use Qt Print Support unless your printer support PostScript. What is your printer model ? So you will need to implement custom solution to send RAW data to printer. Solution will be platform dependent. Please specify your environment configuration. What is OS version? Win10, Ubuntu? What is Qt version? Qt 5.8.0 or something else? What compiler version? MinGW or VC, or gcc ? You are welcome to ask questions. Best regards.
