DEVONthink PE 1.9.3 is using Apple’s new PDFKit to display PDF documents.
Printing a PDF from a DEVONthink view window doesn’t work properly. This is due to a change in Apple’s printing code for PDFKit. The problem will be fixed in a future DEVONthink update.
WORKAROUND: For the time being, launch the PDF document in Preview (or Acrobat) to print it.
Note: This PDF printing problem doesn’t affect users of DEVONthink PE 1.9.2, which doesn’t use the new PDFKit code.
