Can't print in colour from Mac M1 (OS 12.1) to HP Envy Pro 6400!

[FRA-1066]

I can't believe this.  After acquiring my snazzy new Macbook,  I had to abandon my faithful old Canon printer because Canon was not updating the drivers.  So I switched to HP, on the grounds that AirPrint meant I need not worry about updating drivers.

My first week with the HP6400 has been very satisfactory.  And then, I had to print an official document in colour.  

It is not printing in colour!  There is no option to print in colour (unlike on why phone).  In the end I had to transfer the document to my iPhone to print in colour!

Either HP solves the problem or I want my money back.  I see this was first posted as a problem nine months ago.  HP should make it clear on its site if it is unable to make its printers work with modern Macs.

I have just found the answer from an even earlier message, in February last year:

"

Just solved it, I removed and added the printer again in System Preferences > Printers & Scanners (so not only in HP Smart).

"

I hope this helps other frustrated Mac users.  

By the way, why not update the list of Mac systems, so this is not marked as OS unknown?

I have to say also , I have found the app HPSmart a bit problematic.  In order to scan, for example, I have had to download HP Easy Scan rather than scan from HPSmart.)
