I've done this a lot to print out drafts. I have 2 methods but prefer the 2nd:
In word, Layout > Page Setup (small icon bottom right of ribbon box) > Margins > Pages section > Book fold. Then when I print I'll use landscape and select "print on both sides".
In word, save as pdf, then print > booklet (print on both sides selected).
I have an epson printer and both of these methods work okay. If the double sided print still doesn't print, and the "print preview" looks good, it might be a printer settings problem. The links online will be how to print a booklet (or book fold) in word. However double sided printer problems will depend on the make of the printer.
Alternatively, when I want to print an 8 page booklet on 1 sheet I print double sided on a4 with the text in a6 and use a guillotine. That way each page takes up a quarter of the a4 and the booklet can be formed by cutting the a4 in half portrait. If printing pdf I would use "Multiple", pages per sheet, 2x2, page order horizontal and check print on both sides. If printing from word I would use the dropdown 4 pages per sheet at the bottom of the print dialogue.
If you are lucky enough to have access to adobe indesign, there is also a file>print booklet 2-up perfect bound option that works like a charm.
I ended up creating my own template using text boxes in Word.
Like this: 2,5 upside down. 1,6 right side up.
Next page 4,3 upside down. back, cover right side up.
Printed back to back.
In the end, I preferred the look of the original link, despite it being smaller and having blank backs.
I have a manual process
1 first print the odd pages >>>>> you must select reverse print in this step
2 after the printer finishes its task you should hold the printed pages and reverse them clockwise 180
3 untick the reverse print and print all the even pages
