The reason that the PrintDlg() call fails under __WIN32__ is that
sizeof(PRINTDLG) == 68, but the operating system gives an error
message unless you set the pd.lStructSize member to 66.  This, of
course, doesn't happen in the 16-bit Windows 3.x version.  Once
you get the PrintDlg() call to work, you then discover that all
succeeding calls to Escape and TextOut succeed, but the program
still fails to print.  Oh yes, Borland C++ Builder for Windows 95
gives similar results, and substituting more modern calls doesn't
seem to make any difference.
