short Escape(hdc, EPSPRINTING, sizeof(BOOL),lpBool, NULL)
The EPSPRINTING printer escape suppresses the output of the Windows PostScript header control section, which is about 7K. If an application uses this escape, no graphics device interface (GDI) calls are allowed.
hdc
HDC Identifies the device context.
lpBool
BOOL FAR * Points to a Boolean value that indicates whether downloading should be enabled (nonzero) or disabled (zero).
The return value is positive if the escape is successful. This value is zero if the escape is not implemented and negative if an error occurred.
This escape is used only by PostScript printer drivers.
