Acrobat prints sidebar even when no sidebar is visible and page is set to print area only

Hi @Sylvia345215784a90 

Hope you are doing well and thanks for reaching out.

Is this an issue with a particular PDF file or with all the PDFs? Please try with a different PDF file and check. If the file is stored on a shared network/drive please download it to your computer locally and then try again.

What is the version of the Acrobat DC you are using? To check the version go to Help > About Acrobat and make sure you have the recent version 23.08.2042X  installed. Go to Help > Check for updates and reboot the computer once.

Also, try to repair the installation from the help menu (Win Only) and see if that works.

Please try to reset the Acrobat preferences as described here https://community.adobe.com/t5/acrobat-discussions/how-to-reset-acrobat-preference-settings-to-default/td-p/4792082

Also, go through the help page https://helpx.adobe.com/acrobat/kb/troubleshoot-pdf-printing-acrobat-reader.html and check.
