설명

PrintTicket 매개 변수는 개체를 생성 PrintCapabilities 할 기준으로 사용됩니다. 예를 들어 프린터는 입력 bin 1에서 미디어 형식 A 및 B만 지원하며 입력 bin 2의 미디어 형식 C만 지원한다고 가정합니다. 매개 변수가 printTicket 입력 bin 1 PrintCapabilities 을 지정한 경우 반환되는 개체에는 세 가지 미디어 형식이 모두 포함되지만 C 형식은 "제한됨"으로 보고됩니다. 매개 변수가 printTicket 입력 bin 2 PrintCapabilities 를 지정한 경우 반환되는 개체에는 세 가지 미디어 형식이 모두 포함되지만 A 및 B 형식은 "제한됨"으로 보고됩니다. 제약 조건에 대한 자세한 내용은 인쇄 스키마 를 참조하세요.

가 이null면 printTicket 가 UserPrintTicket 사용됩니다.
