Ground Controls->Non_PDF->Print->Options
Thumbnails - This will warn you if someone has turned on Thumbnails. Thumbnails are usually used to do a rough proof a document and are not desirable for the final print job.
Collate - Collate can change the order pages print out in. This may be undesirable in many workflows.
Back To Front - If a job is set to print Back To Front, the pages print in reverse order. This may cause issues with certain workflows.
Include Blank Pages - If blank pages are set to print then this Ground Control will trigger. In some case this may cause useless waste of plates or film.
Print Colors as Grays - If the user has set colors to print as gray, this Ground Control will trigger. Printing colors as grays can cause issues when a job is processed for print as color images usually wind up only as grayscale and show up only on the black plate.
Black & White - If the user has set the job to print as black and white, this Ground Control will trigger. Just like print as grays everything winds up on the black plate.
Color - This is the normal output condition for color jobs and you usually want to leave this Ground Control turned off.
