Layout length limit: 110 inches
Thank you for your post.
The answer by "Fenton Jones" is correct (Thank you!). That is, a standard 8.5 x 11" paper will take up about ten pages on a layout. If you are planning to print 20 or more pages, you can create a second layout that will display pages 11-20. Create a third layout if you need even more pages for a record.
Once your layouts are completed, print the current record using the first layout, print the current record using the second layout, etc. You can also create a script that automatically does this for you, and then attach a button to that script. Once you are happy with the data, click the button, and all pages are printed.
Please let me know if you need clarification for any of the above steps.
