# VAPIMWP_PRINT_PRINTTOPRINTER

Prints the document to the specified printer. This is a parameter of the `VAPIM_PRINT` message.

## Syntax

    #include <kvvapi.h>
    SendMessage(hWndVAPI, VAPIM_PRINT, VAPIMWP_PRINT_PRINTTOPRINTER,
               (LPARAM) (LPCSTR*) lpszPrinterDriver );

## Arguments

Argument | Description
--- | ---
`hWndVAPI` | The handle of the VAPI window.
`lpszPrinterDriver` | A string in the operating system code page that is the name of the printer driver, or `NULL` for the default printer. This string must be of the form `printername, printerdevice, printerport`. For example: `\\Calculus\HP LaserJet IIISi,winspool,NE00`:.

## Returns

`SendMessage()` returns `TRUE` if the call succeeds; otherwise it returns `FALSE`.

## Discussion

- This message prints to the specified printer without calling the common Print dialog box. You can use this message to implement a Print menu item or toolbar button.

- When printing in an application that is a Windows service, a default printer must be installed for the user account using the application.

- To make sure that the entire document is opened before the document is printed, open the document with the `bWait` member in the TPVAPIOpenDocumentInfo structure set to `TRUE`. Use the VAPIMWP_PRINT_CANPRINT message to determine whether the document has been completely processed and is ready to be printed.

- The `printerdevice` in `lpszPrinterDriver` must be WINSPOOL, because WINSPOOL is the output device used by Microsoft Windows for all printers.
