Can someone please help me with borderless printing before I kms

I've spent all day trying to do this.

So I've created a whole load of greetings card designs using Procreate on my iPad with an A4 template at 300dpi.

I have just bought a Canon PIXMA G2501 printer that supports borderless printing.

I have been trying all day to figure out how to print these borderless using an A5 template.

I've tried Publisher and Word.

It just will not work.

This is the best I've managed using an Avery A5 "tall" Word template: https://i.imgur.com/DNNmxnL.jpg

P.s. ignore the quality I'm doing it low qual on shitty paper whilst I try to figure it out.

Thank you.

Great design resource
