HP fax app dose not want to work

[drtomf]

using HP Color LaserJet Pro MFP M277dw Windows 11 will not open the app newly downloaded. Why?

Using the LaserJet Pro , on the panel, I could get it to send what I wanted to send.

Please explain what the issue is

Hi @drtomf 

Welcome to the HP Support Community! We're here to help you get back up and running.

Thanks for explaining the situation clearly—I understand how frustrating it is when a previously working fax setup stops responding after a change. To help isolate the issue, I’d like to clarify a few details:

Which printer is currently having the problem with the HP Fax app?

• Is it the HP LaserJet Pro 400 color Printer M451dn
• Or the HP Color LaserJet Pro MFP M277dw?

What exactly happens when you try to open the HP Fax app?

• Does it fail to launch, crash, or show an error message?

Was the app downloaded from the Microsoft Store or HP’s support site?

Are you trying to send faxes from the computer using the app, or directly from the printer’s control panel?

Is the printer connected via USB, Ethernet, or Wi-Fi?

Once I have these details, I’ll guide you through a focused recovery path to restore fax functionality. Let’s get this working smoothly again.

Take care, and have an amazing day!

Regards,
