Sometimes it is easier to print a document when you need to compare several pages. For example in an offer on page 2 I a proposal for a device and service, but the device-details are on page 5 en the service-details are on page 9. If you'd like to compare why them it's sometimes easier to have the pages next to eachother.

Now I can print the document and lay out the pages next to eachother on my desk, it would be cool if I can do that digitally.
