I think there is a misunderstanding here. I am referring to the desktop app, not a desktop computer. That is, you will never see the print button on Charts Cloud (charts.navigraph.com). You will only find it in the desktop app, downloadable from the Your Account > Downloads > Charts page on our main website.
If I understand your post correctly, you are attempting to access Charts in a web browser, which would mean that you are trying to use Charts Cloud and thus you will not have this button.
Please let me know if you are using the downloaded version and you still see this issue!
Kind Regards,
