Description & Usage

EndPage informs the print spooler that the program has finished drawing the contents of a printed page. The StartPage and EndPage functions must bracket all code which draws the contents of the printed page. The print spooler must have already been informed that it is receiving a document to be printed via StartDoc before drawing the page had begun. The printer does not actually print the page until the print spooler is told via EndDoc that the entire document is complete.

Return Value

If an error occured, the function returns either zero or a negative value (Windows NT, 2000: use GetLastError to get the error code). If successful, the function returns a positive value.

Visual Basic-Specific Issues

None.

Parameters

hDC: A handle to a device context to the printer being used to print the document.
