How to print photos

How do I get a folder of 300 photos on my iPhone printed? I’m having so many issues!

I can’t seem to upload that many photos straight from my phone to wallmart photo. And my iCloud was full, so now I’m paying for more storage just so I can get the photos on my laptop then hopefully upload them easier to wallmart photo

I also haven’t edited them. What would be the easiest way to apply the same filter to hundreds of photos
