How to get Avery Labels to line up in Word 365

 I'm writing this blog post for myself really, because next time I try and print labels I will have forgotten what I did to get them to line up. And I don't want to waste seven sheets of labels trying to work it out - AND I couldn't find any other posts online that told me exactly. 

I am using Word 365 and trying to line up Avery Labels L7160. I have set up a document by click on Mailings (tab in Word), Labels (far right next to envelope), put in my address, then selected Options, selected Avery in Labels Vendor, and looked it up in the list. Then click okay, back to the labels window, select New Document and hey presto you have a sheet of the same addresses. (to enter different addresses, you have to do that manually)

So, I'm ready to print, I think, let's go, and then it doesn't line up.

First makes sure the margins ARE custom: 1.5cm top and bottom, 0.7 both sides. 

Then in Word go to File tab, Print, nad in the next window where it says pages that the A4 option is selected, not letter unless it's the same size.

And even go into Print Properties under the printer and check that is set to A4. 

But the real trick was clicking in the Page setup at the bottom in the same window as above.  

And click on Print Options, which brings up this main window, and under Advanced, Printing (scroll to get to printing), there is this little tricky line that is selected: 'Scale Content for A4 or 8.5 x 11" paper sizes. 

This is NOT the right size for labels. Make sure it is NOT selected.

After that they should print in alignment! 

Hurrah!
