When a worksheet contains a cell with longer text, which is right aligned and this text happens to be in the last column of the page, the worksheet is incorrectly split into pages and the last column gets transferred on the next page.

Workaround: Set explicitly the print area you would like to print.

worksheet.WorksheetPageSetup.PrintArea.SetPrintArea(new CellRange(0, 0, 38, 14));
