Welcome Glenda Cunningham,
Thanks for reaching out to Microsoft Q&A Forum. I understand you want to make sure the app you installed from the Microsoft Store is connected to your HP printer so you can print from it.
To help narrow this down, could you please confirm:
- Which app are you trying to connect to the printer? For example, is it HP Smart, or a Microsoft app such as Word, Photos or Outlook?
- What is your HP printer model, and is it connected through Wi-Fi or a USB cable?
Please make sure you already tried the Q&A Assist steps. In addition, please try the following:
1, Run the built-in printer troubleshooter.
- On Windows 11, go to Start > Settings > System > Troubleshoot > Other troubleshooters, then select Run next to Printer.
- On Windows 10, go to Start > Settings > Update & Security > Troubleshoot > Additional troubleshooters > Printer, then select Run the troubleshooter.
2, Set the HP printer as your default printer.
- Go to Start > Settings > Bluetooth & devices > Printers & scanners.
- Turn off Let Windows manage my default printer.
- Select your HP printer, then select Set as default.
3, Restart the printer and the network connection.
- Turn off the printer, the computer and the Wi-Fi router, wait about 30 seconds, then turn them back on in this order: router, printer, computer.
- On the printer's control panel, confirm that it shows a connection to the same Wi-Fi network as your computer.
Looking forward to your update.
