Hi Serrin,
Welcome to the HP Forums, I hope you enjoy your experience!
I understand you are getting a blank faded area down the middle of the page only when printing from the computer. I will be happy to help you.
Since the printer is printing the tests properly then it isn't a hardware issue, it is probably a setting from the driver or application.
From the software program your printing from check the paper type settings.
Then go to file, select print.
Select the proper printer name, then click Properties or Preferences.
Select the Paper/Quality tab.
Make sure the Paper size is set correctly, Paper type, set it to the type of paper you are using.
(not unspecified)
Try printing again.
Try printing the photo on plain paper to see if you get the same results.
If you require further help please provide the following information so I can help you better.
What program are you printing from?
What kind of paper are you using?
Is it the same paper as the test page printed properly?
What operating system are you using? How to Find the Windows Edition and Version on Your Computer.
Thank you for posting on the HP Forums.
Have a great day!
