[DDempsey82]

Hello,

I installed replacement cartridges for my hp office jet pro 6978. How do I get it to print in color?

Hi @DDempsey82,

Welcome to the HP Support Community. 

I'd like to help!

This issue could occur if the print-in-black-only option is checked in the drivers or the color cartridge may be empty or defective.

Let's go through a few steps to fix this issue.

1. In your software application, click Print.

2. Select your printer from the list of available printers.

3. Click the option that opens the Printer Properties dialog box.

Note: Depending on your software application, this button might be called Properties, Options, Printer Setup, Printer Properties, Printer, or Preferences.

4. On the Properties window, click the Paper/Quality or Features tab, depending on your software.

5. Click Advanced, click Print in Grayscale, and then de-select Print in Grayscale or High-Quality Grayscale.

6. Click OK to complete the change.
