Printer incompatibility with the Golden Gate OS.

Based on user reports, macOS 27 Golden Gate has ‘broken’ printer drivers from several manufacturers. 

The Brother HL-5370DW does not support AirPrint, which is the easiest way to connect to a printer and does not require drivers from the manufacturer, only an AirPrint-capable printer. 

Rosetta 2 (the macOS engine for running Intel apps on Apple Silicon) is needed for some old printer drivers. Even if it was installed on your Mac previously, the upgrade to macOS 27 Golden Gate removed it. If Rosetta 2 is not installed and you launch an Intel app, you’ll be prompted to install it. That is what happened here, when I launched an app that I had used frequently on Tahoe then launched for the first time after upgrading to Golden Gate.

That prompt does not happen with a printer driver. Accordingly, it may help to install Rosetta 2 using Terminal. Apple provides instructions for that HERE. Note that if this enables your old printer drivers to work, you’ve only put off the inevitable. As the dialog box above indicates, macOS 27 is the last version that will support Intel-only apps (and printer drivers). If you upgrade to macOS 28, you will need to find another solution – either a new printer (get one that supports AirPrint), or for example setting up a Raspberry Pi as a print server (not too hard and plenty of tutorials, but the cost will be similar to an inexpensive printer).

If that does not help, then the first step is to reset your printing system. Note that doing so will remove all your printers and you will need to re-add them, but that is Apple’s suggested method to solve printing problems.

Steps to Reset the Printing System

• Open System Settings > Printers & Scanners
• Secondary-click (right-click, two-finger click) in the top two lines or on any printer and select Reset Printing System

• More info: Reset the printing system on your Mac to solve a problem - Apple Support

Since your printer does not support AirPrint, check the manufacturer’s website, and if there are no updated drivers, then you may be able to set up your printer on macOS using a generic driver.

Steps to Connect and Print

• Connect the printer: Plug the printer into your Mac using a USB cable, or connect it to your local network via an Ethernet cable. 
• Add the printer: Click Add Printer, Scanner, or Fax (the + button).
• Choose Driver: Select your printer from the list. In the "Use" drop-down menu, choose Generic PostScript Printer.
• Finish setup: Click Add to complete the installation.
• More info: Add a printer to your printer list so you can use it on Mac - Apple Support

If that does not work, there are two other options:

Option 1: connect the printer to a always-on host computer (like a Mac, Windows PC, or Raspberry Pi) running third-party print server software such as HandyPrint, Onyx, or a CUPS-based solution to share the printer via AirPrint.

Option 2: you may be able to use the manufacturer’s printing app, which is available on the Mac App Store.

neuroanatomist and sberman, the Generic PostScript Printer driver worked just fine for my Brother MFC-L2740DW printer, thanks so much for providing! Much more helpful than just someone castigating printer vendors, LOL, sigh...

I've been using the generic driver with my HL-5370DW and it works for the most part, though it doesn't appear to give me the option for double-sided printing. Perhaps, after 15-ish years, it's time for a new printer. :-)

Installing Rosett2 via terminal solved my printer issue. I have a Brother B&W laser printer. Thanks

I downloaded Rosetta and it works for me. Not a long term solution I realise but now my Brother mono laser printer HL-2132 works after installing Golden Gate.

Apple is not responsible for printer driver compatibility in new operating system releases beyond supported AirPrint models which require no vendor drivers.

Apple provides the printer vendors with the same developer tools that we have access too, and the vendor has every means to test and update their drivers for compatibility — if they are willing, and have not discontinued that printer model support.

They have several months to make their supported printer drivers compatible with the operating system in its beta and subsequent releases. Some vendors are extremely lax in this effort.

Hey, quick tip. Ask your preferred Ai engine to write you a PPD of your printer driver for the Mac Silicone chip. I did. It worked brilliantly. In fact, Ai requested I upload the original printer driver from (/Library/Printers/PPDs/Contents/Resources/) and it re wrote the driver PPD software to bypass the references to the Intel chip. Super thrilled. I truly am as my printer was a very good, twin tray A3 colour laser that I was loathe to trash. Pass this on.

I am having the issue with the Canon Pixma Pro9000 II. So frustrating. Iv'e been using the printer without difficulty with an M1 mini with no difficulty until Golden Gate came along. Desperately need a solution to continue using my trusted, albeit old, pro-level printer.

'Generic PostScript Printer' doesn't appear as an option on the dropdown list. I have lost connection to my Brother mono laser printer HL-2132 since updating to Golden Gate. In fact it shows no generic drivers at all.

I have the same sort of issue with my 3D printer after installing Golden Gate.

Though my MAC and the printer are both connected to the same network via Ethernet and WiFi the Mac dies not find it's IP address in Creality Print.

So I can no longer 3D print!

Chrome can find and connect to the IP but Safari doesn't.

The Brother HL-5370DW monochrome laser printer was released in early 2009!

From AI:

Had the same issue here, although my printer is Fujifilm Apeos Pro.

Apple developers braking printer software every time they release a new software isn't something new...

Not at all helpful.

Glad that helped. Enjoy your Apple gear.

Wow, that worked!
