Epson Printer Drivers supplied by Apple
I have an Epson XP-760 all-in-one printer on a Mac mini, MacOS 10.14.1 (Mojave). I need information and advice regarding the bewildering and confusing printing options available when printing multipage pdf documents, so I contacted Epson. They told me that, since updates to the printer driver are provided by Apple through System Preferences/Printers & Scanners, I should contact Apple. But this matter is too complicated to be satisfactorily dealt with by phone or chat, and I can find no way of emailing Apple with an enquiry of this nature. I should be very grateful for answers to my questions (as below), or information on how to email Apple with my questions.
I want to print a 2-page or multi-page A4 portrait-format PDF document from Preview.app. When I access 'Printer features' in the print dialog, I see both '2-sided printing' and 'Two-sided printing' (which is confusing enough). Whichever combination of settings in these two categories I select, the second side of the document is printed upside down.
If I select both these two options and then experiment with 'Duplex Tumble', I have three more options: 'None', 'DuplexNoTumble' and 'DuplexTumble'. Only if I select 'DuplexNoTumble', do I finally obtain 2-sided prints with the second side the right way up.
I attach a screen shot of the lower part of the list of printing options.
