Software Workshop: Printing a booklet:

Saddle stich binding - Folded pages stapled or stitched down the middle - 
booklet must be a multiple of 4 

Perfect binding - single leaves printed on both sides and ring bound or glued - 
any multiple of 2 

Readers Spread: What you would actually see on the screen if you where reading the booklet, I must get my pages in the correct position before printing, I initially need content on my pages - When looking in the pages option. I have noticed that all the pages have a 'A' in the top corner.

Simply go onto select the left master page and create a text frame:

From here select the drop down menu and follow this down to select Insert Special Character - Markers and the finally current page number.

 As you can see within the screenshots below, once the page number is applied to the master page the rest of the pages in the booklet are numbered accordingly.

To apply these page numbers to the right pages simply hold alt and drag to the right page.

Now moving onto printing the booklet:

First step is to select print booklet - then choose the booklet type - Print settings - go through the normal print settings, selecting paper size always landscape - position of the page marks and bleed 

From here select Printer options

Select two sided - long or short edged binding, this is determined by which edge the bing will be on, - click print and then ok.

I can use the preview to check to see if all my pages are in the correct order.
