/**
* Print an image using the ImageX.dll extension.
* The logic is to determine the approximate page size in inches, then set up a table with each cell measured in page inches,
* generate each table cell as an image from ecw_image.dll extension of the webserver as a JPG, embed in the tables and then
* print it. Since we dont know when setting up the page what the output page size is, we ask the user. We could use the DPI to
* work out the sizex and sizey parameters of the ecw_image.dll for the optimal size of each tile.
