Hi I would like to print the landscape orientation with a Samsung ML-1610 and have also installed the printer drivers related to it but the problem is that it is being printed in portrait mode and the operating system used is Linux opensuse 11.4 and the printer am using is SAMSUNG ML 1610 and the motherboard is asus m3a-h. Provide the solution to this query in fixing the issue. Thank you.
