ok thanks.
If the solution is to server the layers as tms then i´m out of luck because TMS is not working in my installed version of geoserver I don´t understand what "redirecting the willed GWClayers to the related GeoServer layers before they are printed" means.!!?!
I have tried to make a simple html print window in javscript, but now the problem is that the raster backgrounds only work in IE9 on Windows7 and on SP only the vector data can be printed!
I neve knew that printing could be such a head ache!
yours,
Rob

Hi Robert,
So from that link the sentence that is most important is:
The solution is to use OpenLayers.Layer.TMS for the geowebcache layers
rather than OpenLayer.Layer.WMS
So you're WMS layers needs to change to be a TMS layer, if that is
acceptable to you. The other solution is in the next post:
I also went into this problem few days ago. I tried using TMS layers but
without success. The solution I pitched on was redirecting the willed GWC
layers to the related GeoServer layers before they are printed. It's not a
pretty solution, but it works well! [1]
