I downloaded the Fallout Pip-Boy companion app, thinking I could use it offline simply by using the local connection that goes between my wireless printer and my PC. I believe it is technically a Wi-Fi connection, albeit one without internet, I thought it ought to work.
However, when I connect my PC and phone to that network, and then start up Fallout 4, the app says "cannot scan for connections please ensure Wi-Fi connection" or something like that; I don't remember exact wording.
Is it just something I'm doing wrong, or is this actually not able to use a non-internet connection?

Wireless printers that function without a router generally use a special Wi-Fi mode, frequently called Wi-Fi Direct or Wi-Di. It is not a network connection at all; it's effectively a cable without a wire.
The Pip-Boy app is a TCP/IP program; you don't need an internet connection, but you do need a network connection. You may be able set up your computer's Wi-Fi card to create an ad-hoc network (I'm sure you can find instructions on another part of SE for that), but there's no guarantee your mobile device can connect to it.
If you are able to successfully create a network and connect to it with your phone, the Pip-Boy app should work.
