Parameters

OCGId
The unique identifier of the required OCG entry. You can obtain this identifier using the GetOCG method.

Return Value

A member of the PdfOcgState enumeration. The value of the Print state setting. The GetStat method can be subsequently used to determine if this method has been successful.
Remarks
This method is only allowed for use with non-encrypted documents.

It is recommend to use the GetStat method to identify the specific reason for the method's failure, if any.
