Problem with Printing Images in a Form

Hello!

I am currently working on a form in Adobe LiveCycle Designer.  The form has a few PNG images with transparent backgrounds included in it as part of the design of the form.

When I save the form as a dynamic XML PDF, the images appear fine.  But when I print them, they don't look right and appear as artifacted blocks of color.

All of the images are 300dpi 8 bit RGB PNG images.  I have tried embedding the images but it doesn't make a different when printing.  The strangest thing of all is that the the logo prints correctly, but the other images do not, and they all are the same format.

Any help would be greatly appreciated - thanks so much!

Best Regards,

Ashley
