When you are changing the resolution of the photo before you printer.
What software is it specifically that you are printing from?
Ok, so you are printing from Photoshop.. Thank you.
After you change the resolution. You need to make sure that its set to print on 13x19 paper then..
And you need to also Resize/resample the image after you make these changes.
What you should see on screen before you print, when you set it to 300x300 and 13x9 size.. The image should expand and look blocky. ( because y our lowering the quality )

Ive sent an offer for remote support, where I can connect to your mac from here and work directly on this issue on screen. Once Ive repaired the issue, it will be easier to explain and show you what to do on screen, rather then via written word.
Once you have accepted that offer I will send the connection steps.
