설명

초기 PrintTicket 에서 프린터에서 지원하지 않는 인쇄 기능을 요청하는 경우 프린터 드라이버는 실행 가능한 티켓을 생성하기 위해 모든 충돌을 해결합니다.

속성

ConflictStatus

프린터에서 지원하는 기능과 두 소스 PrintTicket의 초기 병합에서 요청한 기능 간에 충돌이 발생했는지 여부를 나타내는 값을 가져옵니다.

ValidatedPrintTicket

PrintTicket 개체를 병합한 결과이며 실행 가능하도록 조정된 PrintTicket 개체를 가져옵니다.

메서드

Equals(Object)

지정한 ValidationResult가 현재 ValidationResult와 같은지 여부를 확인합니다.

GetHashCode()

ValidationResult와 해당 PrintTicket 및 인쇄 스트림에 연결된 해시 코드를 가져옵니다.

연산자

Equality(ValidationResult, ValidationResult)

지정된 ValidationResult 개체가 같은지 여부를 확인합니다.

Inequality(ValidationResult, ValidationResult)

지정된 ValidationResult 개체가 같지 않은지 여부를 확인합니다.
