Debugging a printing problem

This is driving me crazy.  The following code fragment compiles, and works in Windows NT, but when run in Windows 95 it fails.  Specifically, the Print dialog box appears, but when I click the button to print, nothing happens!  I am simply returned to the main program.  Please let me know if you see anything in the code that would not work in Windows 95.  If I can solve this before Friday (Sept. 4) afternoon I will raise the point value.  Thanks,

Mark.

Add the following two lines after DocInf.lpszOutput = NULL;

DocInf.lpszDatatype = NULL;
DocInf.fwType = 0;

These two members of DOCINFO are ignored on Windows NT, but must be initialized on Windows 9x.
