Problemi with plotter

Hi, excuse me for my english...

 I have some problem when I try to plot a dwg with Draftsight. The plotter is a Designjet HP T920. When I plot the plotter give me only a white strip and not plot the drawing area.

If i plot the same dwg  with another printer (Nashuatech) or in PDF (or in autocad 2011), I haven't problem.

Other one have the same issue?

Thanks
