I've received a PDF with an e-signature image placed on a signature line. It looks fine when viewing the document in Acrobat Reader or Acrobat Pro, and the print preview even looks OK. When I send the document to any printer it puts the signature image on a black box instead of a transparent box. I've tried printing to a color printer vs monochrome, tried with and without "print in grayscale" option, attempted printing Document only, Document and Markups and Document and Stamps. I'm not sure what else to look at or what settings are related to how a signature will print. The document is secured so I can't alter any of the properties of the PDF or the signature.
