# VAPIMWP_PRINT_PRINTHEADER

Specifies whether a print header appears at the top of the printed output. The print header consists of a left-justified file name and a right-justified page number followed by the page-length on the next line.

You can change the file name value by using the VAPIMWP_PRINT_SETPRINTNAME message. This is a parameter of the `VAPIM_PRINT` message.

## Syntax

    #include <kvvapi.h&>
    SendMessage(hWndVAPI, VAPIM_PRINT, VAPIMWP_PRINT_PRINTHEADER,
                (LPARAM) (BOOL) bPrintHeaders );

## Arguments

Argument | Description
--- | ---
`hWndVAPI` | The handle of the VAPI window.
`bPrintHeaders` | If `TRUE`, the document is printed with a header. If `FALSE`, the document is printed without a header.

## Returns

`SendMessage()` returns `TRUE` if the call succeeds.
