Positive image is printing as a negative

[fjelly]

I want to print an image that appears as a positive, but it prints as a negative.  I've printed this same image in the recent past and did not have this problem.

Hi! @fjelly, Welcome to HP forums.

I understand when you print a picture from your printer it prints as negative.

Don't worry I'd like to help you out.

Did you make any changes to your printer?

Does the issue persist when you make a copy from your printer?

Are you using new OEM or remanufactured cartridges?

Have you tried printing using a different application? Does the issue persist?
 
Follow the steps below, and let me know if you get better print quality.
 
Note: You may want to run the Clean Printhead process more than once to properly prime the Printhead
 
Align the printhead using the printer control panel.
From the home screen on the printer control panel, swipe left, and then touch the Setup icon .
Swipe up on the display, and then touch Printer Maintenance.
Touch Tools, and then touch Clean Printhead.
A test page prints.
Examine the test page.
If the print quality is unacceptable, touch Clean Again to continue the next level of cleaning. Repeat these steps for the third cleaning stage, if necessary.
   NOTE:
If the printhead is badly clogged, it might require another cleaning cycle. If so, wait 30 minutes before you perform all three levels of cleaning again.
If the print quality is acceptable, touch Done.

Let me know if this works!

Have a great day ahead! 🙂
