Fixed bug: Printing from Prism Mac 5.0 results in blank page. 

This is a bug in Prism that has been fixed in 5.0c.  Update.

If you can't update, It is very easy to bypass the problem by following these steps:

1. Drop the Prism menu and choose Preferences. 
2. Go to the View tab. 
3. Look at the "Reset Zoom..." section. 
4. If  the option is checked and set to "view entire graph", either uncheck the option or choose a different setting in the drop down list. 
5. Drop Prism's  File menu and choose Page Setup.
6. Check that the page size is correct, and that scale is set to 100%.
