printing multiple worksheets

I'm having a problem printing multiple worksheets into one document. I follow the Help instructions, but it still doesn't work. All the worksheets are in the same workbook, but only some of them will print. What could I be doing wrong?

Yeah, a little more info would be appreciated if you wish this to be solved

I right-click on a worksheet tab, click Select All Sheets, click Print, Properties, set the Orientation to Landscape, the Duplex to Open to Left, and Staple to Top Left, then click OK twice. Trying to print all the worksheets into one document, double-sided and stapled. Though it prints all the worksheets, only some of them are stapled, and others only print on one side.
