 I logged this back in 2006 for v1.02, but it (and my account) seems to
 have vanished.  The problem still exists in v1.2.

 To print something out so that it's ACTUALLY at 1:10000, you have to
 fiddle with it until it's around 1:9375...then you can use a 1:10000 scale
 to measure things correctly

 From the user mailing list:
 "I did a quick experiment with DWF Viewer using the Sheboygan sample data
 and the "Plot at Specified Scale" functionality.  The on-screen EPlot
 preview that was generated seems to have the correct scale (I measured by
 hand and assumed 8.5" page width, so screen resolution wasn't a factor).
 I plotted to a scale of 8000, and the scale I computed was 8080.  Some of
 that error I attribute to my on-screen measurements.  When I printed the
 DWF though (at 100%) and measured the scale from the printout I got 8350,
 so a little over 4% error.  I estimated my on-paper measurement error to
 be about 20 units.

 It's possible there's some inaccuracy in the printing code.  To test this,
 I first printed the DWF to an MDI file using the MSO Live Meeting Document
 Writer Driver, and then used MSO Document Imaging to print the MDI.  In
 this case, the scale on paper correctly came to 8000."

 Check the thread "Printing to specific scale doesn't work - wrong scale"
 from July 2006 on the Users mailing list for any more details.
