Is it possible that the printer/copier has (several) built-in rasters (pattern types) and that some time is necessary to calculate which one fits best for the gray shade ? Recall vaguely a laser printer I was using years ago where this was the case if one didn't define in the driver interface which raster type to use. Just thoughts, Sveinn
