This Deskjet should still print color from modern macOS, but the key difference is often what driver macOS auto-assigns when you add the printer. New Macs (especially with newer macOS versions) frequently default to AirPrint or a generic driver, which can cause weird behavior like grayscale previews even when color is selected.
Your Deskjet model does NOT support AirPrint, so using an HP printer driver is a must.
Ok, so how do you find out exactly what driver is using?
- Open System Settings > Printers & Scanners
- Select your HP Deskjet 6988 from the list.
- Look for a line labeled: Kind You’ll see something like: AirPrint, Secure AirPrint, Generic PostScript Printer, or HP Deskjet 6980 Series (HP driver). If it says AirPrint or Generic, that’s usually the culprit.
Alternately, if your comfortable with using commands in the Terminal, you can get more advanced details.
- Open Terminal
- Run: lpstat -l -p
What I suggest that you try:
- Go to Printers & Scanners
- Remove the printer.
- Click Add Printer again.
- VERY IMPORTANT: in the Add dialog, look at the Use:” dropdown.
Try selecting:
- “HP Deskjet 6980 Series” (if available)
- NOT AirPrint if you see an HP-specific option.
So why preview shows grayscale even when color selected?
That’s a sign the driver is exposing the printer as monochrome-only or defaulting to a monochrome capability profile. Safari and PowerPoint both rely on the system driver capabilities, so if the driver says “monochrome,” they’ll generate grayscale previews regardless of your color checkbox.
Finally, if removing/re-adding the printer driver didn't help, I would suggest that you reset the macOS print system.
- System Settings → Printers & Scanners
- Right-click in printer list area (or Control-click)
- Choose Reset Printing System
- Re-add printer and carefully pick the non-AirPrint driver.
If you want, tell me:
- What macOS version the new MacBook Pro is running. Right now, I'm assuming that it is macOS Tahoe.
- What “Kind” currently shows
- Whether you’re connecting the printer via USB, Ethernet, or WiFi
