old MacBook will print color, new one not - ?!?

Thank you Mom for the lovely Christmas gift: MacBook Pro M5 32GB nano screen, mmmmm nice!

Replacing MB Air M2 2022 which I just printed from fine in color.

- The new one won't print color from Safari or PowerPoint, even with "color" selected in the print dialog the print previews are grayscale.

- Printer is an old HP Deskjet 6988. I suspect a difference in the printer driver for this old gal, but how do I even check that?

In other words, how can I find the name/file of the printer drivers?

P.S.: YES the printer is OLD but I hardly use it and when I do pull it out it WORKS WORKS WORKS just fine. I have zero need to buy a new printer. If the 2022 can print color to it it really must somehow be possible from the new.
