IPrintOemDriverUni::DrvWriteAbortBuf method (prcomoem.h)
The IPrintOemDriverUni::DrvWriteAbortBuf
method is provided by the Unidrv driver to allow an OEM rendering plug-in to send printer clean-up code after a user terminates a print job.
Syntax
HRESULT DrvWriteAbortBuf(
PDEVOBJ pdevobj,
PVOID pBuffer,
DWORD cbSize,
DWORD dwWait
);
Parameters
pdevobj
Caller-supplied pointer to a DEVOBJ structure.
pBuffer
Caller-supplied pointer to a buffer containing a code fragment to be sent to the printer.
cbSize
Caller-supplied number of bytes in the buffer pointed to by pBuffer.
dwWait
Caller-supplied length of time the printer must wait, in milliseconds, before it can start a new print job after the current job is aborted.
Return value
The method must return one of the following values.
Return code | Description |
---|---|
|
The operation succeeded. |
|
The operation failed. |
|
The method is not implemented. |
Remarks
OEMs use IPrintOemDriverUni::DrvWriteSpoolBuf to send output to the printer. If a print job is terminated by the user, IPrintOemDriverUni::DrvWriteSpoolBuf
returns E_FAIL and can no longer be used to send any data to the printer. When this occurs, certain printers must have a clean-up code fragment sent to them, resetting their states before they can start new print jobs. For these printers, IPrintOemDriverUni::DrvWritetAbortBuf
is used to send this code fragment to the printer.
IPrintOemDriverUni::DrvWriteAbortBuf
can only be called after IPrintOemDriverUni::DrvWriteSpoolBuf
has returned E_FAIL. IPrintOemDriverUni::DrvWriteAbortBuf
should not be called more than once per job.
Rendering plug-ins are described in Customizing Microsoft's Printer Drivers.
