You can not increase the pixel size of a photo, that is already on your computer, minus reducing the quality of it.

But if you scan at a sophisticated resolution or increase the dots per inch (dpi) then the picture power will be increased. The higher the dpi the better the pic aspect.

Place a photo in the scanner and when the on blind printer program box opens a short time ago look for a place that indicates dpi. Normal dpi is 200 and 300 dpi is quite immense. That is the best i can do sense you dont say what nature of printer you have.

Set the scan resolution to your desire dpi. Scan it. Done. Mean while, remaking the picture on your computer files beside an image editing software will solve this problem.
