Prints should look identical to the view / sheet on the screen...period.
Should be able to print nice, crisp, vector prints, all the time. Shouldn't have to sacrifice shading, colors, use of images / logos, etc because they force Revit to print to raster graphics. Raster prints are garbage.
DWFs (and hopefully built in PDFs in the near future) need to use vector graphics for measuring tools to work downstream. DWF is YOUR (Autodesk) format and you don't really support it!
Modeling isn't the only purpose for using Revit...at the end of the day, we still need to produce documents - please make annotation and printing improvements a top priority!
