Quería saber si hay alguna manera de que no aparezca la ventana de "Imprimir" al abrir un PDF ya que es molesto tener que cerrarla cada vez que abro un archivo. Busqué en internet y en el foro pero no encontré soluciones, ví las opciones del programa pero no encontré nada similar.
When this happens it's because there's a script embedded in the file that's causing the Print dialog to appear when you open it.
You can't remove that script with the free Reader. However, you can stop it from executing by disabling JavaScript entirely, via Edit - Preferences - JavaScript - then tick off "Enable Acrobat JavaScript". Note that this may affect many other things as well, such as calculations, buttons, etc.
