Printing/Scaling issues

Hello,

I am having the following issues:

  1. print preview does not match the sheet layout
  2. printing comes out at a random scale: usually tiny
  3. The size of the viewport (the height and width settings in the "view" menu of the properties panel) keeps resetting itself to random sizes: I tried to make the view tabloid size but it keeps resetting to different numbers. Also, there are no measurement units associated with this feature.....I'm assuming it is in inches even though it is not indicated.... or am I totally wrong about the function of this feature?
  4. the "fit to page" option is grayed out, and I cannot use it at all.
  5. I can't figure out how to pan the drawing within the viewport window.... this is REALLY basic stuff, but I can't make it work...

I have only been trying to print to PDF so this is not device related. I'm a fairly new CAD user so it may very well be a beginners mistake, but I do have experience printing from AutoCAD with  similar options and have always managed to be able to print my drawings to scale.

I'm on a Macbook Pro OSX 10.6.7

 

Please help!
