About printer resolution

Printer resolution is measured in ink dots per inch (dpi). Generally, the more dots per inch, the finer the printed output you’ll get. Most inkjet printers have a resolution of 720 to 5760 dpi, the latter being the smallest dot size a printer can use.

Printer resolution is different from, but related to, image resolution. To print a high-quality photo on an inkjet printer, an image resolution of about 220 ppi should provide good results. Using a lower resolution, you can print a slightly larger photo—if you are willing to accept some image degradation. You’ll see a warning if you chose a print size that causes the photo to print at less than 150 ppi.
