Match Orientation in Corel X6

I would like to inform you bout my problem, i'am cartographer and i'am using Corel X6 for daily work, i used to print normally till i had match orientation problem(in my case i have a report with 50 pages some of the figures are landscape, others are portrait) when i'm trying to print it in my Xerox 550 printer i got only the pages with portrait orientation printed correctly, the ones in landscape orientation are printed wrongly .

I would like to find a solution for my problem as i'm in extremely need of printing.

NB: I'am using windows 7 (64bits), and i dont have the problem when i printed the same report in PDF format.

Please can someone help me?
