Re: HP Envy 5540 printing green instead of black

Hi! , I am the MrRobot. It looks like you were interacting with , but he is out of the office today so I'll take over from here.

I appreciate your efforts for trying out the steps.

As you mentioned the issue still persists after trying out the steps.

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

Are you using an HP genuine ink cartridge or refilled ink cartridge?

 it looks like the cartridge could be very close to empty.

Try the steps recommended below.

Click the printer icon on the taskbar.
Right-click Properties.
Click Toolbox in the Properties dialog box.
Select Open hp Envy Toolbox.
Click the Estimated Ink Level tab.

Refer this article to further troubleshoot print quality issues.

Let me know if this helps!

Have a great day ahead!
