Oh the joys of being one of the first to use a new technology, eh?
I'm sorry that the generic Microsoft driver isn't working for you. I have been trying to work with Microsoft to get a printer driver issue corrected for one of my Brother printers. It won't print in landscape orientation. It just shrinks the page down and prints it on the top half of the page in portrait mode. It took quite a bit of chatting to get escalated to the next level of support but they are supposedly looking into it for me. We'll see.
I am surprised that the generic Microsoft driver for HP printers doesn't work. Especially, because it is obviously able to communicate with the printer in order to initialize it. It almost sounds like the Windows print subsystem may be damaged. To test this, do you have any other printers that you could try to print to? Maybe take the SP11 to a friend's place and see if it will install and print to their printer. It might be worth a shot and will give you another data point. The only bad thing would be is if it wouldn't print on the other printer, you'd probably have to reset Windows 11 to fix the print subsystem.
Hopefully HP will figure out a fix for you. I've read quite a few complaints now about the missing PlugPlay service in relation to HP's printers, so hopefully it will get looked into and corrected soon.
