Hi Zaki

Thanks for reaching out on the Lucid community. A couple of things to note:

• If you have many different page tiles separating your pages and would like your diagram to print onto these separate pages you will need to change your print settings.
• When you go to print the default will have the Paper Size as "Full Canvas" which makes it so that the resulting download is all on one page.
• If you change the paper size this will separate the diagram onto multiple pages as described.

If you continue to experience trouble with this please check out our Adjust Document and Board settings from our Help Center for some additional context. Feel free to send me a screenshot of your print settings so that I can take a closer look if that doesn't resolve your issue. Thank you!

Here are my setting: 

Hi Zaki

Thanks for getting back to me with that screenshot. In this case you need to change your Scale from "Fit to Page" to "100%". Hope this helps!

Thanks that solved my issue
