I have an hp envoy 6000 printer I can't download the app, it says my device is not compatible! It worked fine for several years. I'm trying to connect from my samsung android phone

I assume the 6000 is connected and working but your smartphone cannot run HP Smart

The system requirements for the HP Smart app are:
An HP printer
An HP Smart account
A computer or mobile device with an operating system that meets the following requirements:
Windows: Windows 10 Redstone 5 (version 1809) or later
macOS: macOS Big Sur (11.0) or later
Android: Android (10.0) or later
Apple iOS, iPadOS: iPadOS 16 or later
Some HP Smart features require a network connection and an HP account to work fully.
Here are some tips for setting up the HP Smart app:
Make sure your device's operating system is up to date
Place your printer and device near your Wi-Fi router
Turn on Wi-Fi on your device and connect it to your network
Turn on Bluetooth so the app can find your printer
For mobile devices, enable location services and allow the app to use your location to find your printer

If HP Smart cannot run then use samsung print services

The Samsung Print Service Plugin enables printing from your Android device to your HP printer over a Wi-Fi network, or using the Wi-Fi Direct connection for Wi-Fi Direct supported printers

Wi-Fi Direct can be used to avoid configuring the router. Watch this: 6xxx
Wi-Fi Direct is explained on page 28 of the User Manual, this Wi-Fi setup avoids configuring the router.
