Problem in Color Setting

Hi All,

I'm a graphic designer by my hobby. I'm using corel draw from it's 4th version. Recently I decided to purchase Corel Draw X5. So I download the trial from internet.

But, its disappointed me. When I print text/line art from X5, its prints sharp dotted lines. And the solids are not perfect solid. I opened some files from X4, and same result. But when I create a file in X5 and save it to X4, then print it from X4, its perfect. I'm using a HP LajerJet 5000 & Samsung ML1610 Printer.

What is wrong with Corel X5? or the Color setting?

my setting is :
