Another little trick is to create a duplicate layer, apply a High Pass filter so you see some detail but not much, and make the blending mode Soft Light. Done properly it can sharpen an image non-destructively and allow a larger print.
Yes..GF works very well. But what I am doing is doing a slight offset to the existing pixels and not upsizing. It is similar to having three layers of the same image giving an optical illusion of "3D". The sharpening compensates for the offset. Give it a try!
