GAP ( Gimp Animation Package ) 2.4.0 for Windows XP Vista (and Gimp-2.4.x )
This is not a new plugin but i think useful post the download link
Windows users often don't know how compile from source and this Windows installer is hard to trace even by Googling
Most of links will lead to the only official installer "gimp-gap-2.2.0-set-up.zip" here but that is a obsolete version that will not work with gimp 2.4.)

Every paper size has a different shape, and none probably match the shape of the images produced by your digital camera. This little utility will create a layer showing which parts of an image will fit on the paper when printed. A wide selection of print sizes are included. Using it will help you layout your image so that important pieces aren't cut off by the printer/lab.
This script-fu was developed under Gimp-2.0 and Gimp-2.4
