Where can I get a Brother PT-PT2430PC P-touch label maker driver for macOS Montery ver 12.7.5?

Hi,

At least according to the Brother PT-2430PC support pages, only Windows software/drivers are available for this printer:

So, unless someone has a better solution/workaround, you would have to connect the printer to a Windows computer (running one of the listed operating system versions). Texts produced on a Mac computer (and saved in an appropriate file format) could possibly be transferred (via a network or on a USB flash drive) to the Windows PC for editing and printing.

The situation with only Windows drivers and software appears to be the same on other Brother download sites, except for Japan (where it looks like a Mac driver is available for up to macOS 10.15 Catalina).
