Pixma MG3620 printing size issue

[merbel]

Trying to print a photo in a 4 x 6 size on a letter size piece of paper. Printing from an iPhone. It let me select size for multiple options. I select 4 x 6 and print but it fills the whole page. 
Any thoughts/suggestions?

I am able to put multiple photos on a layout in pages on my Mac and print that way but the color is not true (hope to try to color calibrate my Mac but for now I need to use iPhone or iPad) and don’t want photos for to print full letter size.

Hi, merbel!

So that the Community can help you better, we need to know exactly which version of iOS you're using and which app you're printing from. That, and any other details you'd like to give will help the Community better understand your issue!

Hi,

Are you printing directly from your device or do you have the Canon print inkjet selphy app install? 

We look forward to your reply.
