My HP 5540 prints everything in black and white from my HP windows 11 laptop.  I installed a new color print cartridge and I aligned the print heads and the normal color alignment pate is printed,

I cleaned the print heads multiple times.

I used the HP print doctor and when asked to print a test page, it was black and white.

Hi @tburditt,

Welcome to the HP Support Community! 

Thanks for reaching out about your query regarding your printer!

We're thrilled to have the opportunity to assist you and provide a solution.

Try these steps:

Check Printer Settings

Verify Printing Preferences:

• On your computer, go to Control Panel > Devices and Printers.
• Right-click your HP 5540 printer and select Printing Preferences.
• Check if the settings are set to Print in Grayscale. If they are, switch to Color.

Check Advanced Settings:

• In the Printing Preferences dialog, go to the Paper/Quality tab.
• Ensure that Color is selected instead of Black & White.

Use HP Smart App

• Download HP Smart App from the Microsoft Store if you haven't already.
• Open the app and run a test print. The HP Smart App sometimes overrides printer driver settings and helps diagnose the issue more effectively.

Update Printer Drivers and Firmware

Update Printer Driver:

• Go to the HP Support Website.
• Download the latest driver for your printer model and operating system.
• Install the update and restart your computer.

Update Firmware:

• On the HP Support Website, check for any firmware updates available for your printer model.
• Follow the instructions to update the printer firmware.

Check Cartridge Installation

• Ensure the color cartridge is properly seated in its slot.
• Confirm that no protective tape remains on the cartridge which might block the nozzle.

I hope this helps.
