Print Preview
The Print Preview Dialog is used to display what the printed output will look like. The Print Preview dialog can be used to check whether you have the desired formatting and layout before you print out the workbook. Evince is set up to be the default viewer.
15.3.1. Customizing the preview application
You may change the default preview application by editing your presets for GTK. Open the file .gtkrc-your GTK version and add a line in the format gtk-print-preview-command="command to your preferred viewer".
Please make sure you have only one line defining your preview application.
It is strongly recommended to use Evince as the default viewer. A convincing argument is that Evince deletes the preview file after closing the viewer.
