Image get filled with black hatch

[elasoft]

I'm using the Spire.Pdf version 3.8.8 (newest hotfix).
When trying to print an existing pdf by loading it into a Spire.Pdf.PdfDocument, then calling the 'Print' method of the documents PrintDocument gives an unusable result. The image is covered by a black hatch.
In the attached TestData.zip file you will find two pdf-files: the original.pdf and the printed_with_spire_pdf.pdf.
Any suggestions how to prevent this ugly hatching?

Further investigations have shown, that this is a transparency bug with images. When i replace the images in the pdf with completely transparent images, the areas covered by this images are printed completely black. We used an older free version before that did the transparency correct but didn't render all images (probably those with a transparency ?). We need this fixed as soon as possible.
