Save a single slide as a pdf?

I don't mean to take the food out of Rich's mouth :-) but I'm not sure what he means by "PDF format problem". PPT 2011 most definitely does save to PDF format, whether using Save As or Save as Pictures from the File menu or using File> Print - PDF. For what you've described wanting to do there are at least 2 methods:

Method 1

• To create the single slide file;

1. Open a new blank presentation
2. Delete the default Title Slide
3. Go to Insert> Slides From> Other Presentation
4. Navigate to & select the file containing the slide you want
5. In the Choose a File dialog confirm that Select slides to insert is the option chosen (lower left corner of the dialog)
6. In the Slide Finder, select the slide you want
7. Make sure Keep the design of original slides is checked
8. Click Insert
9. Click Close

[Alternatively, you can copy the slide then Paste to a new file but that may not provide the same result.]

• To create a PDF from the new file;

1. Go to File> Save as Pictures
2. Enter a Name & Location
3. Select PDF from the upper section of the Format: dropdown
4. Click Save

Method 2

1. In the existing file, select the slide you want
2. Go to File> Print
3. Choose the Selected Slides option
4. Select any other Print options as preferred
5. Click the PDF button
6. Select Save as PDF
7. Specify Name & Location
8. Click Save

Method 2 will have a white border surrounding the slide content. However, you probably can tweak the other Print settings to avoid that if you wish, depending on the printer.
