I'd love to add a local scenic backdrop behind our Rally track.

I have a photo and a bit of googling found the answer I was after to be able to print this in A4 sections.

It seems easy enough (famous last words)...

• Open a blank Excel sheet (I use Libre Office Calc)
  
• Define your print page size (mines A4)
  
• Click in the A1 box to highlight it
  
• Click insert>image then find your preferred image
  
• Zoom right out until your preferred poster width is visible - you should see the 'page printable' boxes
  
• Drag the bottom right corner of the imported image down and out to your preferred poster size
  
• When you choose 'print' it'll print your now huge poster in A4 sections
  

I intend covering an area about 2m wide by 1.5m high which my printer tells me is 42 sheets of A4

I've not tried it yet but it should work...
