Hi, While giving the print command using PDFBox, if we add both the Paper Tray and Paper Size in the PrintRequestAttributeSet reference, then the attribute added later overrides the previous one.
For example, we want to print A3 size from Manual Tray, then the attribute added later precedes the older one. This is because both hierarchies belong to a single enum. That is why this problem is there. Regards, Virender
