DPI will only determine the size of the printed image. It will do nothing about quality. So you can use basic math to determine the resolution (PPI-pixels-per-inch actually) as a function of size.
An image that is 3000 pixels wide, when printed at a resolution of 300 ppi will be 10 inches wide (3000 divided by 300). The same image if printed at 3000 ppi will be one inch wide. So if you know how large you want the printed picture to be, you can determine the correct resolution by dividing the actual pixels by the desired size. If you want the image to be 8 inches wide, divide 3000 by 8. The correct resolution for printing would be 375 ppi. You can change the resolution to this value in Photoshop by going to Image >Image Size, deselecting the "Resample Image" checkbox and entering the new resolution in the resolution field. Deselecting "Resample image" will maintain accurate image quality as no information is lost oar added. Only the pixel size has changed.

you can set a number for dots per inch- that’s how priners think- in
photosop elements. So my question is: my printer says it can do 4000 dpi if i want it to. i’m trying to print 7 megapixel photos. how many dpi would be suitable for a 3000 pixel image?
thanks
