Type: WORD Indicates whether the strings contained in the DEVNAMES structure identify the default printer. This string is used to verify that the default printer has not changed since the last print operation. If any of the strings do not match, a warning message is displayed informing the user that the document may need to be reformatted. On output, the wDefault member is changed only if the Print Setup dialog box was displayed and the user chose the OK button. The DN_DEFAULTPRN flag is used if the default printer was selected. If a specific printer is selected, the flag is not used. All other flags in this member are reserved for internal use by the dialog box procedure for the Print property sheet or Print dialog box.
