OS27 update won't print to my Brother LS-L2300D

*Solved* Brother printer works normally now.

Apple's Rosetta was not included in OS27 simply triggering that install fixed everything back to normal.

Fix:

1. Make sure that your Mac is connected to the internet.
2. Then open Apple's Terminal app. You can open by either using Spotlight or use Finder to find it in Applications folder.
3. Copy & paste the below command at the prompt
4. Then press Return

softwareupdate --install-rosetta

MacOS 27 will not print to any printer that doesn't have AirPrint

This is not true. There's no way Apple would do this without publicizing it.

The guess is that your Brother driver is/was x86_64 and that it required Rosetta. From

What's new for enterprise in macOS Golden Gate 27 - Apple Support

• "If Rosetta was previously installed, it will not be automatically restored upon upgrading to macOS 27. Rosetta will continue as a general-purpose compatibility tool through macOS 27."

Too late, but maybe this will help someone else - run:

file /path/to/your/filter

For example:

> file /Library/Printers/Brother/Filter/rastertobrother2300.bundle/Contents/MacOS/rastertobrother2300 

/Library/Printers/Brother/Filter/rastertobrother2300.bundle/Contents/MacOS/rastertobrother2300: Mach-O 64-bit executable x86_64

x86_64, the filter supports Intel processors

Mach-O universal binary supports both Intel and Apple Silicon

Installing Rosetta again may have been all that was needed.

But getting an AirPrint printer is a good solution to avoid driver issues in the future, when vendors don't update their drivers.

Me too with MFC7860DW - my son suggested using add printer to search for anything available and another 7860 came up so I deleted the original, and made the new printer the default and it printed right away. I appreciate your different machine might not work, but might be worth a try as it's simple process.

That printer supports IPP, which means macOS CUPS should work.

FYI, There is another thread elsewhere on the Apple forums which mentioned the CUPS web interface is no longer available. I found mention of this for the earlier Golden Gate betas. I saw someone mention that CUPS may still be running, but maybe there are other things that have changed at least for much older model printers.

Yeah; I’m reading a thread posted elsewhere, and it looks like the CUPS web interface has been bricked.

Deliberately, though undocumented. So much for reading the docs…

I won’t speculate on why.

Installing CUPS from Homebrew might work around the limitation, or a command-line configuration.

Not true, was able to get my HP Laserjet CP2025 to work with the generic PostScript Printer driver.

What software?

Are you opening specific printer software before you try to print?

Does the printer appear in System Settings ➜ Printers & Scanners?

Does the printer not show up in the Print option of any App like Mail or Pages?

The LS-L2300D appears to be a USB printer, so should not require any special software or drivers to print to.

I have the exact same printer. Stopped working after installing OS27. I was using the CUPS driver as well. Print Center says the sofware is not compatible with this device.

Headed on over to Brother's website, they only have drivers for OS26. I installed it, but no go.
