Hi!
Your printer naturally has an area you can't print on. But word also sets limits on where it can print. I make PDF documents with Word that have text on the non-printable area. In order to do this, I do the following:
- Click on File -> Page Setup...
- Now, for Paper Size, choose A4 Borderless, or US Letter Borderless, etc... depending on your page size. (To get this option, hover the mouse over A4 or US Letter, etc..)
- If you have a custom size, select Manage Custom Sizes... at the bottom, select your custom size and input zero for all the numbers under Non-Printable Area
I hope this helps!
Note: I use Office for Mac 2011
