Printing Problem: If printing multiple pages 1st page is good then pages 2+ are super faint. I am running Adobe Acrobat XI Pro and have been using the same program for years with no such problem until just recently.
Hope you are doing well and sorry for the trouble. As described, If printing multiple pages 1st page is good then pages 2+ are super faint.
Please check for any missing/pending updates for Adobe Acrobat XI Pro and try updating it. Go to Help > Check for Updates. You may also download the patch manually from the link: https://www.adobe.com/devnet-docs/acrobatetk/tools/ReleaseNotes/index.html and reboot the computer once. Also please try updating the printer driver and firmware and see if that works for you.
