Hi Hezi,
Thank you for your interest in Essential PDF.
We can set an image as a background for an existing PDF document page by drawing the image with transparency. Please refer to the attached sample for more details.
Currently we don’t have support for printing PDF files, we have already logged this as a feature request. We will let you know once the feature has been updated to our library.
Please let us know if you have any queries.
Regards,
Angappan.
