Problem Pxlmono Ricoh Mp8000

Hi guys.
in Mac pxlmono old this prints very slow aprox.10 min for a single image. with the new pxlmono it prints very fast although if I rotate the image to print, the sheet comes out blank, ", only if I turn it".
If I delete "-dNOINTERPOLATE in FoomaticRIPCommandLine" it prints fast though again if I rotate the image the sheet goes blank, only if I turn it.
Am I lost in something? Thank you.
