Hi Robert, So just a quick one;
the error gwc request that you sent initially: http://maps.zgb.de/geoserver/gwc/service/wms?BBOX=1176787.0%2C6892762.5%2C1181754.1%2C6899536.0&HEIGHT=625&WIDTH=458&map_resolution=75&SERVICE=WMS&REQUEST=GetMap&STYLES=&TILESIZE=%7B%22w%22%3A256%2C%22h%22%3A256%7D&TRANSPARENT=true&VERSION=1.1.1&FORMAT=image%2Fpng&PROJECTION=EPSG%3A900913&format_options=dpi%3A75&LAYERS=zgb%3Atk50&SINGLETILE=false&SRS=EPSG%3A900913 doesn't work obviously, as you established. What I was saying about stripping out the gwc part is that if you replace http://maps.zgb.de/geoserver/gwc/service/wms? with http://maps.zgb.de/geoserver/zgb/wms? you will get a request that works: http://maps.zgb.de/geoserver/zgb/wms?BBOX=1176787.0%2C6892762.5%2C1181754.1%2C6899536.0&HEIGHT=625&WIDTH=458&map_resolution=75&SERVICE=WMS&REQUEST=GetMap&STYLES=&TILESIZE=%7B%22w%22%3A256%2C%22h%22%3A256%7D&TRANSPARENT=true&VERSION=1.1.1&FORMAT=image%2Fpng&PROJECTION=EPSG%3A900913&format_options=dpi%3A75&LAYERS=zgb%3Atk50&SINGLETILE=false&SRS=EPSG%3A900913 That is, in essence, what you have to do programatically whenever you want to print. Does that make more sense?
