The GIF & JPG color wiring diagrams have landscape format and are sized for 8" X 10" printed output. The GIF diagram has superior image quality & works well when printed on 2 "portrait" pages (10" high X 16" wide) or 4 "landscape" pages (16" high X 20" wide). There are 9 registration marks to help with "sectioning" each page for printing. You may need to change the RESOLUTION setting in your image editor/viewer to 240 or 300 pixels to fit the GIF image to the paper size. It may be necessary to choose "fit image to page size" when printing. Some image editing programs allow changes to the image's height, width & paper margins when printing. This is how I managed to print 2-halves or 4-quarters of the 8" X 10" image to give an enlarged diagram. If your browser doesn't display the GIF file properly, right-click on the GIF file link and click "save link as" to download the file to your computer. Your local copy center may be able to produce large prints on over- sized paper. Ask for a more permanent ink than ink-jet printers use.
