Where has the booklet printing option gone?

Hi there,

Updated to Big Sur when released (on a 2019 MacBook Pro). Went to print a booklet the other day and found that there's no option. When I expand the Layout option in MS Word or Preview, I can do Two Sided Printing but only have the option to do long or short sided printing:

When I try and print from Pages, same issue:

I haven't updated my printer, it's the same one I've used for about 6-7 years and have always been able to print booklets from it before. Have checked for latest printer drivers and have updated all I can. Have removed the printer and reinstalled it, no change. I can only assume this is a Big Sur related issue.

Anyone have any idea what's happened? I really found that feature helpful and I really rather not install a third party application just for this if it's some setting I'm missing in the OS.

Thanks
