where is "use only settings from printer preferences" option?

I am a very new user trying to print to my Brother QL-700 label printer. I am using LO 6.4.03

I am having problems setting up the page size and in particular the size shown on the print dialogue (File ->Print) does not agree with the settings in printer properties.

I gather that I need to set the “use only settings from printer preferences” option but I can’t find this anywhere. Its not on the “More Options” Tab in the printer dialogue and I have searched all the other menus I can think of. I found some discussion on line about this option being moved - is it still available?

I am currently trying to print from Calc but I have also looked in Writer and I can’t find the option there either.

Thank You
