Photo Printers Dpi Fast And Easy To Use. Walmart Photo Quality (dpi)?

Walmart photo quality (dpi)? - photo printers dpi fast and easy to use.

I would like to know the quality of photo printers that use at Walmart and / or Walgreen and / or Costco. Look around, everything is "high quality", while I to know square dots per inch (DPI) that counts.

Thank you.
