Open the indicated URL and attempt to print it. The curves constituting the data and frame print correctly, but all the text objects are inflated from 12 points to approximately 72 points.

Reproducible: Always

Steps to Reproduce:
I am able to reproduce this poor behavior on Windows XP SP2 by printing the linked document to either my HP inkjet or the Adobe PDF writer. I am confident this will work with any printer.

To see the problem, activate the "Print Preview..." and adjust the scale to see some more bad behavior.

1) Set the scale to 600% using a custom scale. This will show virtually exactly what prints: the coordinates and curves don't scale but the text does. I would guess this is because of the 6x sampling difference between the screen and the print rasterizer.

2) You will also observe that changing the scale does not scale the image. This is not a problem when actually printing after scaling, so it may be a different but related bug. 
2a) This is especially apparent if you scale down to 30% and notice the extreme clipping. When actually printing a down-scaled image, it appears as a miniature of the preview displayed at 600%.
Actual Results:  
If I actually print (as opposed to using the preview) with the scaling enabled, the graphics are correctly scaled and the fonts are oversized. This mismatches with the preview, which doesn't scale the graphics and 

Expected Results:  
Clearly, all coordinates need to undergo a transformation corresponding to the scale requested. SVG support is great, so I hope we can get the printing straightened out.
