In word I print the odd pages then put the paper back into the printer and print the even pages. I've done it this way for over a decade.
My printer is an Epson BX635FWD (firmware up to date). My OS is Yosemite and I can't do back-to-back printing from a multi page Word (MS Word for Mac 2008) document. I want to print page 1 with page 2 on the back, etc. I have no problem printing a multi page web document. I do ctrl+P and the dialogue box offers 2-sided printing, but when I do ctrl+P for a Word document, the dialogue box doesn't offer the 2-sided printing. I would welcome help to solve this. Thanks.
