incomplete print out

Hi there. Good day. I’m a new member of your site and I'm sure you guys can help me regarding printing in SAP. I tried to print some open items in SAP in a landscape format, but when I see the print outs, each page is missing the lower portion. Almost four lines are missing. I tried to print on a portrait format and it was successful. My manager wants to print the data’s in landscape. Is there a page set-up in SAP where I can change the spacing of each line? Maybe that can be a solution. Your response is greatly appreciated. Thank you.
