Hi Peter Short,
I’m sorry this has been so frustrating, especially if this was working normally before and then changed after a recent update. At this point, I recommend that you review and try the steps provided in the AI generated answer on your thread. That reply typically include the most relevant checks for this scenario.
To help narrow this down, could you please let me know a few details?
- What is the exact printer brand and model?
- What is the brand and model of your Windows device?
- Does this happen in every app, or only in one specific app when you try to print?
- When you open the print settings, do you still see the Flip on long edge option, or is it missing/greyed out?
- If you go to Settings > Devices > Printers & scanners > select your printer > Manage > Printing preferences, is double-sided / duplex printing still enabled there?
If possible, please also try a quick test by printing from another app such as Notepad or WordPad, and share a screenshot of the Printing preferences window. That can help a lot.
While my initial response may not fully resolve the issue, I truly appreciate your cooperation as we work together toward identifying the most effective solution. Thank you so much for your understanding.
