SYMPTOMS
ActiveX Document containers that use the IPrint interface to print an embedded Word document may generate one of the following error messages when calling the IPrint::Print method:
This problem occurs if the ActiveX Document server is Word 2002 (Microsoft Office XP), and the client that uses the IPrint interface is out-of-process. The document may print, but you may report that the document cannot print, and you cannot obtain out parameters (such as the number of pages printed) from Word.
CAUSE
Word 2002 accidentally deletes the DVTARGETDEVICE* parameter that is passed to the IPrint::Print method. For out-of-process clients, this causes the proxy/stub code to fail on the return of the function because it tries to marshal the structure data back to the client. Although the proxy/stub DLL traps the access violation, it does not return any of the other return values to the method call and then issues the HRESULT error.
In-process callers to the method do not see this error, but the pointer that is passed to the Print method is no longer valid, and these clients may see their own access violation issues as a result.

STATUS
Microsoft has confirmed that this is a bug in the Microsoft products that are listed at the beginning of this article. This problem was first corrected in Office XP Service Pack 3.
MORE INFORMATION
If you have to maintain compatibility with all versions of Word 2002 and cannot rely on the fix, you may be able to work around the problem. To do this, pass NULL for the DVTARGETDEVICE* parameter. In this situation, Word uses the default printer of the user as the target device. Because there is no information to marshal for the structure, the error does not occur.
If you have to specify a non-default printer before calling IPrint::Print, follow these steps:
- Call QueryInterface on the embedded Word object for the IDispatch interface and then use the Application property to get an IDispatch interface to the server application.
- Use the ActivePrinter property on the Application object to set the printer name of the printer that you want to use. The string must be in the form: "[PrinterName] on [PortName]". For example, you may use "HP LaserJet 5si on LPT2".
- Call IPrint::Print with NULL for the DVTARGETDEVICE* parameter.
Steps to Reproduce the Problem
Note To reproduce the problem, you must have one of the following:
- Word 2002 and an ActiveX Document container application
- Another client that is designed to use the IPrint interface
- Download and then build the FramerEx Microsoft Visual C++ sample that is available through the following Microsoft Knowledge Base article:
268470 SAMPLE: FramerEx.exe Is an MDI ActiveX Document Container Sample Written in Visual C++
Modify the CFramerDocument::PrintDocObject function of the sample (print.cpp ~line 247) to display the results of the print:
hr = pprnt->Print(PRINTFLAG_RECOMPOSETODEVICE, &ptd, &pgset, NULL, static_cast<IContinueCallback*>(this), 1, &cPagesPrinted, &nLastPage); // Code added here to demonstrate IPrint::Print problem for Word 2002. // Word incorrectly frees memory belonging to the COM layer in ptd // marshalled across apartments. When the stub tries to marshal the // target device back across the wire, it hits an access violation. CHAR szbuffer[512]; if (FAILED(hr)) { wsprintf(szbuffer, "IPrint::Print returned error 0x%X! (PagesPrinted = %d, LastPage = %d)", hr, cPagesPrinted, nLastPage); } else { wsprintf(szbuffer, "IPrint::Print returned successful. (PagesPrinted = %d, LastPage = %d)", cPagesPrinted, nLastPage); } MessageBox(NULL, szbuffer, "IPrint Test", MB_SETFOREGROUND | (FAILED(hr) ? MB_ICONHAND : MB_OK));- Compile and then run the sample. (To do this in Microsoft Visual C++, press F5).
- On the File menu, click New Object and then click Microsoft Word Document.
Add some data to the blank document. - On the File menu, click Print to print the document. Select a printer and then click OK.
When the print occurs, one of the errors in the "Symptoms" section appears. Note that the number of pages that are printed (cPagesPrinted) is 0 although the print may have been successful and one or more pages may have printed.
