cups issue on mac os 27

I found this from Western Kentucky University:

"CUPS Admin is a native macOS app that puts back the CUPS web interface (http://localhost:631) Apple removed in macOS 27 — cupsd, lpadmin and IPP Everywhere queues all still work, only the browser admin page is gone. The sidebar lists every queue with its state and active jobs; select one to see its status, hold, release, move or cancel its jobs, and change its default options the way the old "Set Default Options" page did, including per-driver settings like Ricoh user codes. Common changes (color or black & white, duplex, Letter paper, a user code, the default printer) are one-click Quick Actions, and every change is read back from cupsd so nothing fails silently. It ships with cupsadmin, a command-line tool for scripts, Mosyle/Jamf/Munki commands and quick checks. No third-party dependencies; builds with the Xcode Command Line Tools alone."

Apple has restricted or removed functional support for the CUPS web interface menus in macOS 27 (Golden Gate), making traditional administration via localhost:631 fail with a "Web Interface is Disabled" error even when the standard terminal command is used. 

Try this

Use the Command Line: You can still add, configure, and manage printers directly in the Terminal app using the standard lpadmin command-line utility. 

Check Technical Updates: Review deployment notes and workarounds on the paper cut knowledge base regarding handling CUPS changes on newer macOS builds. 

System Settings: For basic printer management, use the native Printers & Scanners section within macOS System Settings instead of the web interface.

¿Any help on the Apple Developer forums?

I use cups so my till drawer opens with my star tsp100 printer. After upgrading, the till drawer no longer opens and I can't get into admin on the cups page. The printer works but I need the settings from cups. How do I do this?

That article is just an AI summary of all the forums where this has been discussed.

Having to query the system with `lpoptions` and then configure things with `lpadmin` is no substitute for the ease of using the web front-end.

What next -- use `defaults write` instead of System Settings?

All of the SwiftUI code that I have in Xcode 27.2 Playgrounds now fails in macOS 27.2 because there is no libcups.dylib found anywhere. How to resolve this Playground issue with SwiftUI code since Apple no longer installs this expected library?

I could install cups from homebrew to get this dylib, but would rather not if there is an alternative.

There's nothing on the Papercut website, other than "it doesn't work".
