Thanks Moonshine and GMayor for trying to help with this. Appreciate it.

GMayor: I downloaded that template, but my printer requires the envelope to be printed in portrait mode, #10 envelopes won't fit horizontally. So when I go to Layout> Orientation & change it to portrait, the Stamp box in your template disappears.

Moonshine: That's interesting that your Word cuts off the box for you in the preview. I am able to insert a box and move it to the top right, and it still shows it as such during the print preview, see below:




Also, when I tried changing the Feed Method as you showed in your screencast, the hortinztal option wouldn't work, as a #10 envelope won't fit horizontally in the printer. It has to be vertical:



Regarding the minimum border on printers, right now it is printing the stamp box 7/8 of an inch from the right edge (22mm). Even though I place the stamp box at the very very edge in Word.

I know the printer is capable of going closer to the edge than that.
It's strange, there must be some way to manually trick the printer into printing closer to the edge. I don't know why this turned out to be so challenging.
