A practical guide

Choose how a file opens and prints.

  1. Add one PDF and read its current preferences.
  2. Change the layout, panel, title or print fields, or keep the existing value.
  3. Save a copy and open it in a viewer to check the result.

Try this example

A booklet should open with two pages side by side and print on both sides of the sheet. Set the layout and the duplex field, then save a new copy.
