gtk:settings-gtk-print-preview-command (object)

object -- a gtk:settings object
setting -- a string for a command to run for displaying the print preview

The accessor for the gtk-print-preview-command slot of the gtk:settings class gets or sets a command to run for displaying the print preview. The command should contain a f placeholder, which will get replaced by the path to the PDF file. The command may also contain a s placeholder, which will get replaced by the path to a file containing the print settings in the format produced by the gtk:print-settings-to-file function. The preview application is responsible for removing the PDF file and the print settings file when it is done.
