creates very large print spool files (10-20MB) and takes more than 2 minutes to print.  Why?  Please help, this is killing us. We print over 100 drawings per day.  In the print dialog box, I always un-check the print shaded box and check the print 1 to 1 ratio.  I tried checking the "draft" box and it printed fast but lines were faint and couldn't see them.
