Printer and HP Scan compatibility with forthcoming macOS update?

[jimpal]

A couple of times on my M4 iMac running Tahoe (MacOS 26.4.1) I have received fleeting little windows (disappear before I have time to read) saying I must update something if I want to continue using my Envy 7155 printer or HP Scan app after a forthcoming update to macOS. I see the word Rosetta now and then. What's going on? If I must do some updating, where can I find an explanation for it that I am able to read before it disappears? By when must this be done, if it applies to me?

Hi @jimpal 

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

Your HP Envy 7155 printer and HP Scan app will continue to work on macOS Tahoe (26.4.1), but Apple is phasing out Rosetta support in upcoming updates. This means that older Intel-based drivers or apps relying on Rosetta translation may stop functioning unless updated. The solution is to ensure you are using the latest HP App and drivers, which are fully compatible with Apple silicon and macOS Tahoe.

Steps to Ensure Compatibility

Update to HP App (formerly HP Smart)

• Open the Mac App Store.
• Search for HP App and install the latest version.
• This replaces HP Smart and ensures compatibility with macOS 26.x.

Update Printer Drivers and Firmware

• Open the HP App.
• Select your Envy 7155 printer.
• Go to Printer Settings > Advanced Settings (this opens the Embedded Web Server).
• Check for firmware updates and apply them.

Reconfigure HP Scan

• In the HP App, select Scan.
• If prompted, allow installation of updated HP Scan components.
• Test a scan to confirm functionality.

Reset HP App if Needed

• Go to System Settings > Applications > HP App > Reset.
• Re-add your printer in the HP App.

Take care, and have an amazing day!

for Hawks_Eye: Thanks for your clearly stated instructions, but I ran into a problem with them, and stopped before completing them.

I proceeded to download the new HP app, opened it with my printer, went to Advanced Settings, and then as I proceeded, up pops a window saying "This connection is Not Private." with a button to proceed as well as an alternative explanation I did not understand. So, I didn't feel I could safely proced without the possibility of some kind of malware.

I'm stopped. What should I do next?

[jimpal]

for Hawks_Eye: Your email today provided the same response to me as yours yesterday. Did not address the problem I have having in carrying out your previous instruction. I'm sure you sent it inadvertently. 

Your previous instructions were very clear, but when I tried to follow them, here's what showed up on my computer when I went to Printer Settings>Advanced Settings today, and Printer Settings/Advanced Settings>firmware updates yesterday:

I'm stopped. What should I do next?

Hi @jimpal 

Thanks for all your efforts and patience.

That “This connection is not private” message you saw is expected when accessing your printer’s Embedded Web Server (EWS). It appears because the printer uses a self‑signed certificate rather than one issued by a public authority. It is not malware, and it is completely safe to proceed when you are connecting directly to your own HP printer on your home network.

• The warning is about certificate trust, not about malicious content.
• HP printers ship with their own certificates, which macOS doesn’t recognize as “trusted.”
• Since you initiated the connection to your printer’s IP address, there is no risk of malware.

Continue with the steps in the HP App:

1. Open HP App → select your Envy 7155.
2. Go to Advanced Settings (EWS).
3. Apply any firmware updates.
4. Re‑add the printer in the HP App if needed.
5. Test printing and scanning to confirm functionality.

You’ll be fully prepared for Apple’s upcoming changes to Rosetta support, and your printer and HP Scan will remain compatible with macOS Tahoe.

For Hawks_Eye: Thanks for your latest. I went through the steps and found I have no firmware updates available.  

Interestingly, I did an Apple update to macOS 25 today on my M4 iMac, and again received the same popup warning about the need to take actions to be prepared for using the Intel HP printing setup with Apple's forthcoming update (was it this one, or an upcoming biggie?). Strange, as these settings were all as they are now. Perhaps it's there if needed or not?

Please take this as a constructive comment. I went through all of these steps (some quite obscure to find) to ensure the future compatibility. Seems like I am there. But I am a quite experienced Mac user. How about the great masses of people who really aren't into the details of making their Mac/HP hookup work right? They wouldn't have had your advice, or even how to get it. HP should wrap all of this up in a new release of your app that does it automatically. That's the way Apple would do it. And, being someone who has respected HP for years, I'm surprised HP hasn't. I suggest that be considered beccause it will save lots of problems.

Thanks for the help.

Thanks for replying @jimpal 

It’s good to hear you’ve already taken the steps to confirm firmware and driver readiness, and that your system is functioning as expected after the macOS 25 update. The popup you mentioned is part of Apple’s transition messaging—Apple is preparing users for changes in how Intel‑based printer drivers interact with future macOS releases. At present, your HP printing setup remains supported, and the HP App continues to be the recommended path for printing and scanning on macOS.

Your observation about the complexity of these steps is valid. HP’s current guidance is to ensure users stay updated through the HP App, which integrates Diagnose & Fix and driver management. 

This approach is designed to reduce the need for manual intervention. Your suggestion that HP streamline this further is constructive.

You are already well‑prepared for upcoming changes. If you notice any new prompts or compatibility warnings after future macOS updates, the first step will always be to check the HP App for updates and run Diagnose &

I see the same error as the OP - the error appears to reset and appear once after every macOS system update (I'm currently on macOS Tahoe 26.5.1.) It appears the first time I launch a scanning application--and although I have the current version of the HP app, I don't use it--whether Image Capture or a third-party app that (like most scanning apps) is built on macOS' underlying framework. The error says that HP Scan 3 will not run on macOS 27 Golden Gate (because it is so old that it is an Intel-based app that requires Rosetta to run on Apple's M-series processors). 

My question: why is HP Scan 3 even being launched when I use Image Capture or a third-party scanning app? Can I just delete it (and if so, where is it - I don't see it in my Applications folder)? Or, if needed, how do I replace it with a current application that will interface with macOS' scanner framework?

Note: I have an HP LaserJet 200 colorMFP M276nw running over AirPrint

I tried the steps you suggested, unsuccessfully:

When I click on Printer Settings in the HP app, I get an error that "Printer settings unavailable. The available printer settings can not display right now. Make sure the printer is connected to a network." This is even though the printer is online, and supply levels show up in the HP app. In macOS's Print Center, "Show Printer Web Page" shows the embedded web server, but there is no option there to update the firmware. However, I am pretty sure I have the most current firmware for this printer--a new version hasn't been released in quite some time.

When I go into the Scan section of the HP app, I just get a spinning wheel, even though I can scan successfully using Image Capture or other applications.

I can't reset the application settings - under MacOS 26, there is no System Settings > Applications in which to access settings for the HP app. 

Again, I don't need to get the HP app to work for scanning... I just want to make sure I have the most current components for macOS's scanner framework to work with Image Capture and other apps it supports. 

Thanks!

As an update, per the advice from @Kuroi_Kenshi in this thread, I tried deleting the folder /Library/Printers/hp (actually, I just moved it out of the Library folder). (Note that the suggestion in that thread to go 'directly to the HP Support website and download the full feature driver package for your printer model' does not work, because for my printer model, it does not give me a choice to download macOS drivers, only Windows drivers.)

After this, and deleting the printer from the Printers & Scanners system settings, and restarting both the Mac and the printer, I re-added the printer. It found the printer driver, and I am able to print successfully.

However, the printer will not scan.  When I open Image Capture or a third party scanning application, I get this error:

The operation couldn’t be completed. (com.apple.imagecapture error 4294957375.)

Using the HP app, when I click Scan, it identifies the name of the printer, but after a spinning circle for some time, it says the scanner is not available. 

I then moved the "hp" folder back into /Library/Printers/, and things work again with Image Capture or third party apps, but not with the HP app. But nothing in the "hp" folder has a modified date later than November 2021. And the applications in there list Kind: Application (Intel). And to the extent we should be relying on the HP app to install a version of the HP Scan component for apple chips,  the fact that the HP app can't access the Printer Settings or the Scan module is preventing this. Can you give any help?
