Set the order in which pages are printed.

 The print_across method is used to change the default print direction.
 This is referred to by Excel as the sheet "page order".

     worksheet.print_across

 The default page order is shown below for a worksheet that extends
 over 4 pages. The order is called "down then across":

     [1] [3]
     [2] [4]

 However, by using the print_across method the print order will be
 changed to "across then down":

     [1] [2]
     [3] [4]
