A family of Microsoft word processing software products for creating web, email, and print documents.
It has never been possible to do this in Word. When started, Word always defaults to the Windows default printer and the settings selected in the printer Properties, and it is not possible to save specific settings with a given document (Publisher can do this). If you were doing this before, you must have been using a macro. If you are selecting these settings through the Printers folder in Windows, they should be the default for all applications, not just Word.
To clarify, no settings in the Print dialog (or the Backstage Print tab) can be saved in Word or with a document. Settings that can be saved with a document are found in the Page Setup dialog. These include tray settings and of course paper size.
