I experienced the same issue with converting powerpoint slides directly to pdf files and I've come up with a solution that does not involve changing the page or print settings.
- Save the powerpoint as a JPEG image.
- Open the image in Preview.
i. File > Save As > JPEG
ii. On the Quality bar, select "Best"
iii. Re-save the image.
iv. Convert THIS image to a PDF.
This procedure produces a "full bleed" file.
So far, I've only used this technique to produce posters (single page powerpoint) that I print on standard letter size paper. I'm not sure how this technique would hold up with multi-page powerpoints or posters that need to be printed on larger paper.
Good luck!
