Hi.

A printer that works fine wired trough USB has been added a generic adapter at its USB jack that allows Wireless.  How to tell Windows 10 to recognize the printer is now in wireless mode ?

There is no WiFi  routers nor other wireless networks related in the premises.  A PC and a now wireless printer.     [ PC<------>printer ]

 

For a 'normal' wireless printer to work with only one single PC;  is a wireless router needed ?

No you should just be able to connect to the printer. But you say the printer doesn't normally support wireless.

So the printer isn't normally configured to use the USB jack as a Wi-Fi adapter meaning the printer might require additional software in order to run the Wi-Fi adapter. Are you sure the generic adapter supports a mobile hotspot?? There is a specific type of adapter you can get called a wireless print server https://www.lifewire.com/wireless-product-equipment-818274

You never mention if your PC has WiFi capabilities.

May be a daft thing to point out, but still, ...

Two things:

1. As fiveworlds says, you need to check that the printer is designed to work with an external Wi-Fi adapter. 

2. If it is, then you need to set the connection up as an ad-hoc network (i.e. not using a router). This may mean changing the settings on both the printer and the PC. 

Thanks to all of you, guys.

The PC is a modern one with built-in WiFi and enabled, and tested working fine..

The printer is old without WiFi capability from factory.  An USB-to-WiFi adapter is much newer than when the printer was designed,  has been added/plugged to it.  The adapter supplies its own 5V for operation and for 'plugged-in'  detection at the printer receptacle

That USB-to-WiFi adapter is proven working, allowed WiFi internet to a laptop in another scenario, with zero setups, drivers or anything.  Plugged in and performed.  It works like a 'bridge'.  Transceives USB 'language ' over WiFi signal.

Will explore the ad-hoc setting.

I doubt very much that the printer supports network access using an external Wi-Fi dongle. I would put money on it.

Check the specs/user manual of the printer.
