Hi cookd2,
If you use PS client, you can use Batch plot to print all dwf files one time, (use "Adobe PDF" printer and set output folder, you will not be prompted to input pdf file name then).
If you use vault client, you can download all the dwf files that you want to print and open "Autodesk Design Review", from File menu, there is "Batch Print Wizard" function that can batch plot them.
