[OS X Emacs] Setting up wireless printer in hotel room

[Bill Rising]

Hi all,

How does one set up a wireless printer in a hotel room so that 

  multiple computers can print to the printer wirelessly
  the computers do not need to switch back and forth between the network that sees the printer and the hotel router, so that printing is not a headache.

One of the computers is running macOS. The others are stuck on Windows.

From what I could find online, it would be necessary to get a router, and then hook that router to the hotel router in bridge mode. [1]. The computers would then hook to the bridge and the bridge would then connect to the outside world or the printer or from computer to computer.

Unfortunately, the posting from HP as well as other less-explicit postings say that this may or may not work depending on the hotel's system. So... there are two questions:

Is 'hook a router up in bridge mode' the way to get (essentially) a subnetwork going within the hotel room?

Is there a way to figure out if this will work before plunking money down on a router?

Thanks for any insights,

Bill

[1] There is a post on HP's site [2] which talks about hooking up a tp-link tl-wr702N wireless nano router which explicitly states that the router needs to go into bridge mode, so I'm using engineering induction to mean that putting any router in bridge mode is the solution. This particular router would be poor choice, because the multiple computers will need to be able to be streaming schoolwork simultaneously and it has pretty limited bandwidth.
