WMS layers just print fine with QGis! The only limitation with this approach, is that not all WMS Server allow to 
produce very large images. By default something like 2000x2000 pixels for Mapserver, but hopefully you can change it. 
Many people have processed images as big as A0 with 254 dpi with Mapserver, so it's should not be a problem.
