72dpi is the 100% in PDFDebugger and in the renderImage() call with 1 parameter or with scale 1. Printers usually have a higher dpi. AFAIK desktop printers have 1200 dpi. The first LaserJet printer had 300 dpi.
A cheap label printer has 203 dpi.

Is there a way to increase this programmatically? I'm still not sure what
the 72 dpi is, is this something that can be adjusted?  The contents of the
PDF are predominantly vectors, so I would expect the document to scale up
properly as it does for all other applications I've tested.
