PowerPoint Printing PPT to PDF without losing quality

[Watapana]

If I manually save a slide to pdf using "microsoft print to pdf" , the quality of print is perfect.
If I use the ActivePresentation.ExportAsFixedFormat with FixedFormatType:=ppFixedFormatTypePDF
the files are blurry. Size-wise first method gives me 1,200 kb file, using vba the file is a mere 250 kb.

Any suggestions?

Solved Intent parameter value needs to be set to :ppFixedFormatIntentPrint for high resolution.

Constant	Description
ppFixedFormatIntentPrint	Intended to be published online and printed.
ppFixedFormatIntentScreen	The default. Intended to be published only online.
