Hi, i have problems with my plottings, whwn i plot to PDF, also to my plotter Cannon IPF 605.The preview is ok, but when it comes "out" the "paper" has turned 90deg. ??Last week i uninstallaed the "Cute pdf whrither" and installed Bullzip instead, and i worked wery fine, until to day  i What can i do?

The first thing I would recommend would be for you to try using the built in DWG to PDF.pc3 Printer/plotter instead of either the Cute or Bullzip driver.
 
This will verify for you first that the driver is not the problem.

There are only two places where one can specify the orientation of a plot.  That would be inside AutoCAD itself and the other is within the properties of the printer being used.  Have you checked both?

Hello, well done John, it's after all these years of PDF from AutoCAD that I did realize that what I've been doing on other programs was applicable directly to AutoCAD instead of having to rotate each file from portrait to landscape !!!
When you lauch a print from AutoCAD to PDF, go to properties, go to customized properties, go to disposition and there you have portrait OR landscape.

I works  hooray!  how silly i have been not dooing this at first time. thank you wery much.
