[Users] Prjection and print preview

[gbrun]

Ok, so no need to use Proj4JS to solve this problem. I only set a new  
center point for my printPage in the same projection as my map. Then, to  
display this print page at the good scale, I choose the appropriate scale  
 from the print provider. And it works!

printPage = new GeoExt.data.PrintPage({
	printProvider: printProvider
});

// A layer to display the print page extent
pageLayer = new OpenLayers.Layer.Vector('printLayer');
pageLayer.addFeatures(printPage.feature);
// New coordinates to center the printPage
var lonlat = new OpenLayers.LonLat(671000, 6276000);
printPage.setCenter(lonlat);
// Add the printPage to the map and choose the appropriate scale
map.addLayer(pageLayer);
printPage.setScale(printProvider.scales.getAt(2));

I hope this will help someone.
