In the Print Objects dialog box (the default report) in the page footer section I uncheck the "Page Number" and "Date/Time" boxes then close the dialog. When I then reopen the dialog these two boxes are checked again. All other boxes remain as they were when the dialog was closed.

Not saving if Cancel is used (or close in Windows) is "by design". However there's some merit in (optionally) saving print option changes if the dialog is cancelled/closed.

Fixed. (a) some settings that were checked by default in the printing script could not be turned off and saved (e.g. Page Number and Date/Time footer items). Now they will be saved. (b) if you cancel/close the print dialog after changing some of the settings, you'll be given the option to keep those settings.
