can not print page in landscape orientation

[Alexey Monakhov]

Hello,
I have problem -  I want to print page in landscape mode,
the page is this one
 http://www.tnt3s.ch/s3/data/test/label-landscape.pdf

I rotate it and print
 PDDocument outputPDFFile = new PDDocument(); ;
            for( PDPage page: l ){
            page.setRotation(90);
                outputPDFFile.importPage( page );
            }

           outputPDFFile.silentPrint(printJob);

but got this error

WHY?
and the thing is that if I do not rotate it I can print without any problem
( but in portrait orientation only.

any ideas?
