How do you print borderless with a 7900e envy inspire printer?

Hi, so I just got this printer and the print quality is a lot better than my last, but it prints everything with way too large of margins. I know its supposed to be able to print borderless, so i wanted to do that, but I can't find the option for it anywhere. Here is what it looks like from the hp smart print window

But as you can see, the HP smart print window not only doesn't print borderless ( the "scaling" only either shrinks or crops, the "photo size" has either full page or select sizes, none of them letter size, and weirdly enough the full page one is worse than some other options ) 
Also, you'll notice that everything is black around whatsbeing printed-- it's not printing transparency correctly, it blacks it all out. But that's kinda ok tbh, because it seems to print transparency fine from the Windows print window, but that print window has even less options than the hp smart one.   So I'm really stuck on what to do here.

In my experience, this is usually a printer software issue, but I have no idea what other software I could be missing, I would expect the hp smart setup to install everything usually and my printer is entirely online and downloaded its own update.
