Detailed Description

Printer port interface.

This interface is used as the base class for the various types of printer port. New printer port classes should be derived from this class.After allocation and construction, a pointer to a concrete printer port should be passed to CPrintSetup::StartPrintL().

Member Function Documentation

Cancel()

virtual void CPrinterPort::Cancel ( )

pure virtual

Cancels an outstanding WriteRequest() operation.

WriteRequest()

virtual void CPrinterPort::WriteRequest ( const TDesC8 &  aBuf, TRequestStatus &  aRequestStatus  )

pure virtual

Writes data asynchronously to the printer port.

Parameters

aBuf	Data to be written to the port
aRequestStatus	A reference to the request status object. If the request is cancelled, this should be set to KErrCancel; if the request completes normally, this should be set to KErrNone.
