This site uses Scalar vector graphics (SVG) to display some graphs and plans. Some older browsers do not support SVG and some of the newer versions will not print to scale. If you are having problems viewing or printing the graphics the simplest method is to install the latest version of either Opera or Firefox browsers which both have native SVG support.
SVG has been a standard for some time now but has not been widely used. I've tried this site with some versions of some browsers but browsers are constantly being upgraded. No browser will currently print a large SVG image full size across multiple pages.
|Opera||10.10||Displays embedded SVG as a scaled image. Stand alone pages are displayed in a scrolling window||Prints documents true to scale. Will only print one page containing the visible part of the image. Print preview options|
|Firefox||3.5.7||Displays embedded SVG as a scaled image. Stand alone pages are displayed in a scrolling window||Prints documents true to scale. Will only print one page containing the visible part of the image. Print preview options|
|Google chrome||7.0||Displays embedded SVG as a scrolling iframe window. Stand alone pages are displayed in a scrolling window||Scales the drawing to fit the page so accurate print outs are not possible. No print preview options|
|Safari (Windows)||5.0.3||Displays embedded SVG as a scrolling iframe window. Stand alone pages are displayed in a scrolling window||Scales the drawing to fit the page so accurate print outs are not possible.|
|Internet explorer||9.0||Internet explorer 9 introduces support for SVG.||Initial tests indicate that the SVG documents are printed to scale.|
Most of the drawings have a scale in each direction or a grid. The size of these should be checked with a ruler before a print out is used. The print settings will generally need to be set to 100% and any "fit to page" options disabled.
The Wikipedia SVG page discusses browser support and some of the options.
