When viewing an analytics report, you can simply use the "Export to PDF" button found in the upper right of the screen to export the current report as a PDF.
All Tabs / Pages of the report are combined into one PDF.
Limitations
The exporting functionality has several limitations:
Currently, only PDF exports are supported.
Some articles that include large tables that show scrollbars will still show scrollbars in the final export. These scrollbars do not work because it's just an image.
Only the default filters that were applied when initially viewing the report are applied, any filters applied to the report by a user cannot be applied to the exported report.
Some reports can take a while to export, do not close the browser tab until it is finished.
