'File not found [-43]' when printing a contact sheet.

You will get this error when you choose 'Hi Rez' thumbnails in the print dialog and the original images are not available. 'Hi Rez' renders the printout from the original images, so either mount the images or turn off 'Hi Rez' thumbnails. With 'Hi Rez' turned off iView Media will print using the thumbnails contained within that catalog.
