we are having trouble printing PDFs using a HP Color LaserJet CP1515n over USB (although we are not dependent on this specific device) on an EFUS A9 module.
We already managed to get the appropriate HDC and draw something with GDI functions which was correctly printed (https://msdn.microsoft.com/en-us/library/ee503887.aspx).
Unfortunately PDFs are another matter altogether. Is there a way to convert PDFs to an image format (e.g. PNG or BMP) or is there another way to print PDFs under WEC 2013?
