How to print on Mac computer from Affinity Photo

[Phenie]

Can someone tell me how to print in Affinity Photo?  I have accidentally stumbled upon ways to print my file at times, but when I do, it doesn't allow me to choose a size.  Can anyone walk me through this?  Thanks!

Hi 
You can do this more than one way, but I think this is the simplest way, at least to explain. ;)

I go file>print

Then I get the dialog and choose "show details"

 

Then you chose the size of your picture.

If you need to resize the piciture you have to do this first:

 

Document>resize document.
