3: * PROGRAM: GETPDRIV.C
4: *
5: * PURPOSE: Handles display of information returned by call to
6: * GetPrinterDriver. GetPrinterDriver is called for the
7: * currently selected printer (in the tool bar comobobox),
8: * and the results are formatted and displayed in a dialog
9: * box.
10: *
11: * FUNTIONS: GetPrinterDriverDlgProc - handles messages for dialog
12: * DisplayPrinterDriverInfo- retrieves & displays printer
13: * driver info
