A:Answer I checked the specs on HP's web site and the printer isn't rated for legal paper, but it *is* rated for size A4, which is about 0.2 inches narrrower than A4, I think it might work, but you'd need to try yourself to confirm.
re: Google Cloud Print--YES, this printer is definitely GCP ready and it works perfectly with Cloud Print. Configuring it was very easy to do as well.
