I'm working on my first web app, and have a simple version of the application working. It allows the user to create and edit a fantasy map from a set of terrain tile images - but I can't figure out how to make it print. A print preview (and an attempted print) shows just a blank page (or a blank page with the background image), but no sign of the existing map. The map is generated as a simple HTML table with each tile being an <img>.
The application uses the dojo toolkit for organization and several utilities, so I suppose it /might/ be related to that, but I seem to get the same problem without using Dojo. Do HTML tables with no data other than a background image print at all?
