Auto-Rotate Pages automatically rotates pages based on the orientation of the text. For example, some pages (such as those containing tables) in a document may require the document to be turned sideways to be read. Choose "None" to disable the Auto-Rotate Pages option. Choose "All" to rotate all pages in the document based on the orientation of the majority of text. Choose "Single Page" to rotate each page based on the direction of the text on that page.
Here you can define the output document resolution. Usually, a higher resolution setting will result in larger but higher quality PDF, while a lower setting will result in smaller but lower quality PDF. You can enter a value from 72 to 2400.
Important: Low resolution is ideal for screen viewing. However, if high-quality paper print or the accurate control of character position is required, you should choose resolution above (include) 600dpi.
Set the overprint true or false
