WM_PRINT
The WM_PRINT message is sent to a window to request that it draw itself in the
specified device context, most commonly in a printer device context.
WM_PRINT
hdc = (HDC) wParam;
uFlags = lParam;
Parameters
hdc
Identifies the device context to draw in.
uFlags
Specifies the drawing options. This parameter can be one or more of these
flags:
Value
| Meaning
| PRF_CHECKVISIBLE
| Draw the window only if it is visible.
| PRF_CHILDREN
| Draw all visible children windows.
| PRF_CLIENT
| Draw the client area of the window.

Remarks
The DefWindowProc function processes this message based on which drawing option is specified:
if PRF_CHECKVISIBLE is specified and the window is not visible, do nothing, if
PRF_NONCLIENT is specified, draw the nonclient area in the given device context,
if PRF_ERASEBKGND is specified, send the window a WM_ERASEBKGND message, if
PRF_PRINTCLIENT is specified, send the window a WM_PRINTCLIENT message, if
PRF_PRINTCHILDREN is set, send each visible child window a WM_PRINT message, if
PRF_OWNED is set, send each visible owned window a WM_PRINT message.
