SET PRINT OPTION supports double sided printing option. I know the docs say it 
is “Windows Only” but it work on macOS for me printing to an HP 451 laser 
printer using 4D v17.0 and macOS 10.13.6. Have you tried this option on your 
Mac?

Paper names can be an issue cross platform. I settled on using the “Paper 
option” with 2 longint values for pixel width and pixel height. That works 
cross platform for me. So 8.5” x 11” would be (8.5*72) or 612 and (11*72) or 
792.

It failed when trying to change from portrait to landscape. And on macOS you 
could set the scaling to like 75% and that would also not work on Windows if 
you save the print setting on macOS and they tried to use that with PAGE SETUP 
on windows. 

Getting printing to work cross platform can be a little voodoo sometimes. You 
have try different things to figure out what works and what doesn’t. I’ve spent 
many hours over the years trying different things on macOS and Windows to get 
report to print correctly as 4D has changed from v2 to v17. That’s a lot of 
versions and that’s not including all the Windows and macOS versions mixed in.
