title: Objects appear as black boxes when printing a PDF from Excel
body: <p>OK. Stackoverflow... i think this will be a tough nut to crack even for you!</p>
  
  <p>I'm running Windows 7 with Office 2010. I've designed a Userform which users can fill out. The user form consists of a regular Worksheet, Formulas, and some Form Elements (not the active-x kind). All works well until I try to print it as a PDF. Then the Form Elements all appear as black boxes!</p>
  
  <p>I'm using the Microsoft Office Native PDF printer and am required to do so (as i have some code that can be executed).</p>
  
  <p>I've searched the net and only found two threads (<a href="http://www.justanswer.com/microsoft-office/6uf3y-excel-2010-professional-prints-black-triangles-areas.html" rel="nofollow noreferrer">here</a> and <a href="http://communities.ptc.com/thread/13773" rel="nofollow noreferrer">here</a>) in forums that even discuss the topic. Neither thread had useful answers. One thread claimed that the issue is with Excel (which i believe) and that it disappears with SP2. I have SP2 installed and that does not take care of the issue.</p>
  
  <p>Here is a screenshot of what it looks like:</p>

  <p>Does anyone know why this happens and how to solve it?</p>
  
  <p>Thanks!</p>
