IPrinterScriptUsbJobContextReturnCodes::DeviceBusy method

  • Article

Returns a value of '3' to inform USBMon that the device communication channel isn't accepting data at this time.

Syntax

HRESULT DeviceBusy(
  [out, retval] UINT32 *value
);

Parameters

value [out, retval]
Value that indicates that the communication channel isn't accepting data at this time.

Return value

This method returns an HRESULT value.

Remarks

DeviceBusy is a read-only method. A returned value of '3' doesn't indicate a failure, and USBMon should inform the print spooler that the device is busy. USBMon can then call the function again at a later time. The number of bytes processed from the print data stream (printData) is returned in the writePrintDataProgress object.

Requirements

Minimum supported client: Windows 8.1

Minimum supported server: Windows Server 2012 R2

Target platform: Desktop
