* Generally speaking, putting something onto the internet doesn't entitle you to make reproductions/copies/prints for your personal use, at least in US law and I believe in most European jurisdictions. You can usually see this with photographers who may sell you the rights to your photos in addition to/alongside any physical or digital prints they sell you.
IANAL, but hot damn is this community aggressive to people suggesting they would pay for things.

Displaying it publicly in a place of business may run afoul of fair use though.

While you're unlikely to be sued for printing off something you don't have the right to make a copy of, you definitely don't have the right to make prints of whatever you find on the internet.
If you have any references that say that, I'd love to see them. Specifically, I'd like to see anything that says that printing a contents of a publicly accessible website for personal use and not to distribute or sell is a violation of copyright. I'm not a lawyer, but everything I read in the Wikipedia article I linked to says otherwise.
The printed version would be transformative, the image is from a published work, and printing it does not harm the market value of the image. That's why I linked it, because it's substantially the same argument.
