Thank you for your response. I made the setting default to duplex print
through cups printer management. Unfortunately it still prints as two
single sheets even with the default and the 'print' interface window
specifying duplex.
But I should not have to go to cups management or to the printer web
management to set duplex on or off. This surely is done by the system
through the 'print' interface. It certainly used to do that. I could print
a document from LibreOffice single sided and then another duplex without
having to go through any printer management. It seems to me that the
appropriate settings are not being sent by the 'print' interface as
appropriate to the 'print' interface completed by the user saying duplex.
It is frustrating.

Hello Turtle,

The printer is a Brother HL-2270DW. I have upgraded to the latest Brother drivers, created a 'new' printer to use, yet the problem persists. I tried printing under Windows 10, which works perfectly, so it does not look like a H/W problem. I have reconfigured cups and the printer using YAST. It still does not work correctly. I have looked in CUPS configuration files but found nothing I could see to be a problem.
To get it to print duplex I have to go to the printer (via IP address and browser) to specifically set duplex mode. Then I have to unset it back afterwards.
I'm using basically the same setup, slightly different Brother printer. Please go to the CUPS management page (localhost:631) select the printer -> Management -> default settings (may be called different, I have german installation :-) Two-sided -> long-edge binding -> Save
You may change this in the KDE print dialog as well, but this will not change the default setting.
