Hello, goral1990
Welcome to the Microsoft Community!
Thank you for your feedback. I have read the information you have provided. You mentioned that you want to download the latest version of the driver package so that you can update the driver without internet connection.
You can download the driver package from this official HP website, you can look here to see if the driver package you want is available, if the file you want to download is not available here as well, then you may need to contact HP support for more help. The download link is below.
