Printer skips pages when printing double-sided

[brynsmith12]

I purchased my printer about a year ago and have never been able to successfully print double-sided. Every time I try it either skips pages (for example, prints page 1 on the one side and page 3 on the back side) or it cuts off text halfway down the page. I am pretty sure all of my Microsoft Word settings are correct so I'm not sure if there is a printer setting issue I'm missing or if it's a faulty printer since I have never successfully printed anything double-sided. Thanks.

Welcome to HP Support Forums. I came across your post and would like to assist. 

I understand that you have an HP OfficeJet Pro 8720 All-in-One Printer and it is unable to perform two sided printing correctly. 

Let me know if the issue persists while using multiple applications to perform duplex printing?

Ensure that the correct paper type and paper size is selected before printing from your Mac computer.

While you respond to that. I recommend you to review the steps as described in detail from this HP document to perform duplex printing in the Mac OS environment. 

If the issue still persists then please continue to perform the following steps to isolate and fix this issue:

• Download and update the firmware on the printer via this HP link.
  NOTE: The printer needs to be restarted once the firmware is successfully installed. 
• Also, update the Mac OS.

You may now try to perform a duplex printing. If the problem persists then let us remove and re-add the printer as Airprint in the Mac OS:

Step 1: Remove multiple printers from the printer list

Check for multiple devices in the Printers list, and then remove any extra entries other than one in idle status.

1. Search the Mac for Print, and then click Print & Fax, Print & Scan, or Printers & Scanners in the list of results.

2. Find the printer names that match your printer from the list of devices.

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. Leave one 'idle' printer in the list that matches your printer if available and use this printer as the Default printer.

4. Try performing duplex printing

   • If the printer prints, you can stop troubleshooting.

Step 2: Delete the existing print queue and add the printer

Remove the printer queue from the list of printers, and then add it again. Doing so creates a new printing session.

1. Make sure your Mac is connected to the Internet.

2. In the Printers list, click your HP printer, and then click the Minus button  to delete it.

3. Click the Add button .

4. Find and select the name of your printer from the Printer list, and then click Add to add your printer. Do not select an HP Fax driver.

      NOTE: If your printer does not display in the list, make sure the printer is connected, turned on, has power, and is ready to print.

5. Click Print Using or Use.

6. Select the name of your printer (if available) or AirPrint.

   Your new printer queue displays in the Printers list in an Idle status .

7. Try performing duplex printing again.

   • If the printer prints, you can stop troubleshooting.

I sincerely hope this fixes the issue. Keep me posted for further assistance.

All the best!
