My printer does the automated double-sided printing and one day it just stopped working and only prints single-sided even though the settings are set to print on both sides.

I have gone through your Post and I would like to help
May I know which App are you using for printing?
Please ensure your Mac and Printer have the latest updates
Printer Firmware: https://support.hp.com/in-en/document/c02919168
Mac update: https://support.apple.com/en-us/HT2015
After checking all those details, Remove and Re-add the printer using Airprint. AirPrint is an Apple technology that helps you create full-quality printed output without the need to download or install drivers.
1.) Click the Apple menu, click System Preferences, and then click Print & Scan or Printers & Scanners.
2.) Check if your printer name displays in the Printers list, If your printer is listed, click the printer name, click the minus sign to delete the printer.
3.) If you see multiple printer queues for the same printer, remove all extra printers by selecting them one at a time, and then clicking the minus button at the bottom of the list.
4.) Click the plus sign , click Add Printer or Scanner, click the printer name.
5.) Click the Use or Print Using menu, select AirPrint or Secure AirPrint in the pop-up menu. Then click Add.
6.) Try to 2 sided printing
Let me know how it goes😊
