The screen argument specifies a CAPI screen on which to display the dialog. The owner argument controls which interface owns the dialog. If it is specified it should be a currently displayed CAPI interface; it defaults to the current top level interface.
The general options that are available are described under install-postscript-printer. In addition, printer-specific options (which are defined in the printer PPD file) are available.
The printers that are visible in the dialog are defined by files in the directories in the list *printer-search-path*.
