LDicomPrintSCU::GetPrinterConfiguration

#include "ltdic.h"

L_INT LDicomPrintSCU::GetPrinterConfiguration()

Queries the Print SCP for the printer configuration information.

Returns

0	The printer configuration information was retrieved successfully.
DICOM_ERROR_PRINTSCU_FAILURE_STATUS	The response of the Print SCP specifies a Failure status code.
DICOM_ERROR_PRINTSCU_CLASS_NOT_SUPPORTED	The Printer Configuration Retrieval SOP Class is not supported on the Association.
> 0	An error occurred. Refer to Return Codes.

Comments

The function will not return until it receives the response of the Print SCP, or an error occurs. The function LDicomPrintSCU::GetLastOperationStatus can be used to obtain the status code specified in the response of the Print SCP. When the return value of the function GetPrinterConfiguration is 0, then the printer configuration information was retrieved successfully, with either a Success or Warning status code in the response of the Print SCP.

The retrieved printer configuration information is stored in the data member LDicomPrintSCU::m_PrinterConfiguration, which is an LDicomDS object.
