Generic PCL Laser Printer driver with macOS 15.1.x

MacOS Sequoia Community,

Upgraded (purchased) new M4 Mac mini macOS 15.x.x to find the Generic PCL Laser Printer driver selected for my very old Brother HL-2270DW does not fully support duplex printing although the duplex option is presented during installation to suggest it should.

Question: Brother stopped providing support for my laser printer long ago, is there a better, more fully functional Generic PCL Laser Printer driver available elsewhere for macOS 15.3.x?

Question: Is there a means to have the macOS 15.3.x Generic PCL Laser Printer driver fixed?

Question: If I'm forced into purchasing a new printer (due to forces obsolescence) how do I determine which printers support macOS Sequoia?

Thanks.
