Borderless printing

I am running Pages 7.3 in Mojave 10.14.2. I cannot get it to print A4 borderless photographs. I use a borderless capable Canon MG7550. I can choose borderless in Page setup but the choice does not remain — it seems to disappear as soon as I leave Page Setup.

I used to be able to print A4 borderless in previous versions of Pages. That stopped when I upgraded to Mojave which will not run Pages' older versions.

Apple, please correct this bug.
