Picture in background shifting when printed

an aerial image that is referenced in the background of a drawing is shifting significantly when printed. any ideas why?

Hello - is this image using the Wallpaper in a viewport, a BackgroundBitmap, or a Picture surface? What is the printer?
Can you please run SystemInfo in Rhino and post the results?

Hello - thanks - if possible can you post a file with just the Picture in it here or to tech@mcneel.com (please include a link back to this topic) - I guess we need to see it happen. In the meantime it would not hurt to get the latest version, which is 6.30:

Images show the layout screen in rhino, the print settings window and then a similar area on the exported pdf.

Hi Riley -

Could you please upload the 3dm file?
