Whether this is true or not doesn't matter, the image is stamped " dpi" now, and the printer driver will honor it. Most software will allow you to specify the 8 inches directly, and then it will compute the ppi for you. This is just a number to be used for printing later.

The image pixels did not change, the image size in pixels did not change, and you will not see any change until you print it using this new number for printed resolution. But since you scaled it to dpi, then it will print at 8 inches, simply because there are pixels, and 8 inches is how far they will go at dpi. Don't let it be hard. Don't make it be hard. If you have an old dpi laser printer that prefers dpi images, this dpi image is a bit more than is useful and pixels will be discarded, but it will print at 8 inches.

If you have a printer that wants dpi, dpi is not enough pixels to be maximally sharp, but it'll be fair quality, and it will be 8 inches. You wanted 8 inches, remember? What do I mean by the printer "prefers" dpi? That's just my cute way of saying that on this specific printer and paper combination, you can see quality losses if you print images with less resolution, but cannot detect quality gains if you print images with greater resolution.

Digital cameras are getting larger, but most still produce relatively small images. Printing larger prints requires a few million more pixels in the CCD cells. Printing requires a lot of pixels, and the same scaling rules are applicable to any image, including those from digital cameras.

Therefore, if the digital camera makes an image that is pixels in length, and if you want to print it at 10 inches in length on paper, then that is obviously only about dpi.

Some users may judge these dpi prints as "great", but a larger image scaled to print at dpi will be noticeably better in quality. Pixels count. Image programs have been quite confusing in the methods offered used for resizing, perhaps because they try to make it easy for us.

They work in pixels, rather than physical dots, which blurs the definition of what does dpi mean. But for the purposes of this article, you just need to know that you can't just download something of the internet, and assume it is printable at the size it appears on your screen.
