[OpenLayers-Users] Generate image

[Albert]

Hi! I'm trying to generate an image of a map that has a WMS layer and an
OpenLayers.Layer.Vector of features that are markers. I followed the
"Tile stitching" method in http://trac.openlayers.org/wiki/Printing. The
problem is that i can generate an image of the WMS layer, but the
markers are not showing as they belong to a layer that is not tiled.
Anyone has any idea of how to do this?
Thanks!
