Hi Guthner,
Thank you for using the Support Forum. The latest word is that they hope to have it posted by mid December. But as you know that can always change. In the meantime you can add the printer on macOS using the built-in “Generic Postscript PPD”. Please consider contacting your support centre for further assistance.
When will a new print driver be available for the new version of Mac OS. Now that it is purely 64 bit, all I get is junk when I try to print.
