Q: using HP DeskJet F2120 All-in-one printer scanner copier
A: You can use the paint application in windows. Click on start > All programs > Accessories > Paint Open the image in windows paint program. Click on image >stretch skew ( give a number smaller, say 50, 50 in the box front of stretch, Horizontal and vertical) press OK. Then save it as jpeg file with another name so that your original file remains intact. Check the final size of the image after saving. Repeat the procedure with the original image if you want it still smaller or bigger, by reducing or by increasing the stretch value.
