Printing upside down in duplex regardless of the selected flip [HP smart]

[Shub007]

Hi,

I have HP323sdnw laser printer. Using pc works fine for duplex but when using mobile (HP app) for printing, regardless of the selected flip (long flip) it still prints upside down (short flip)

Hi @Shub007,

Welcome to the HP Support Community.
 

Thank you for posting your query. I will be glad to help you.

I understand how frustrating it is when your HP Laser MFP 323sdnw prints perfectly from your PC, but when you use your mobile device via the HP app, the duplex print flips incorrectly, even when you select “Flip on long edge.” It’s like expecting a book to open normally, only to find the pages upside down.

Let’s walk through the steps to fix this mobile duplex flip issue.

Fix: Duplex Printing Flips Wrong Edge from Mobile (HP App)

1. Use the Correct Duplex Setting in the HP App

When printing from mobile:

• Open the HP app.
• Select your document → Tap Print.
• Tap Print Settings → Go to Layout or Print on Both Sides.
• Choose “Flip on long edge” (portrait binding) or “Flip on short edge” (landscape binding).

⚠️ Issue: Some versions of the HP Smart app do not honor the flip setting correctly, especially on Android. This is a known limitation with certain printer models and mobile drivers.

2. Workaround: Print via PDF Viewer Instead

Instead of printing directly from the HP App:

• Save your document as a PDF.
• Open it in a mobile PDF viewer (like Adobe Acrobat).
• Use the system print dialog (not HP Smart).
• Select “Print on both sides” → “Flip on long edge.”

This often respects the duplex orientation better than the HP app.

3. Update HP App and Printer Firmware

• Make sure your HP app is updated to the latest version from HP App – For HP Printers, Laptops, and Tech Accessories | HP® Official Site.
• Update your printer’s firmware via: 
  • HP app → Printer Settings → Advanced Settings → Firmware Update.
  • Or visit the HP Laser MFP 323sdnw Printer | HP® Support.

I hope this helps.

Take care and have an amazing day!
