After buying a new iMac, can I use Apples’ $150.00 gift card on a future purchase of an HP printer?

I can’t find info about whether or not this gift card Black Friday deal has to be used on an actual Apple product. I have my eye on an HP printer on the Apple website.
Thanks folks

If the HP printer is on the Apple website, you can use the Apple Gift card for whatever you want.

Only thing I have heard a rule about is that AppleCare purchased with gift card must be done in-store. Guess we will find out more on Friday!
