Samsung SL-M2070FW - Configure communication over Wi-Fi without a router

Hello.
Please help me configure the connection of the SL-M2070FW printer with a computer via Wi-Fi.
I want it to happen without using a router.
There are 3 connections to choose from when running the program from the CD. Via USB, on the network and wirelessly.
Choosing wirelessly, the program does not find a printer (it does not matter if the panel has a button from Wi-Fi or not). When the program does not detect the printer, it has a USB cable connected to it and then it is detected by the program, but it does not help with the configuration of the wireless connection.
By enabling the program that was installed on your computer after this procedure - Samsung easy menager, you can enter the wireless network setting options and turn on Wi-Fi direct there. This program only sees the printer via a USB cable.
The computer sees the Direct wireless network and you can connect to it after entering the password provided in the program but after a while, the computer disconnects the network and connects to the previous network (phone providing the Internet). Turning off the hot spot on the phone gives nothing.
At this moment, printing is done via USB.
Is there anyone able to help me with the configuration?
It's nice if someone showed step by step how to do it - what to put in the program.

I do not want a router that we will use only to print.
As I understand it well, you can do it through Ad-Hoc without a router.
There is a phone that provides internet, you can use it but this is the last resort because when the phone will be behind the house you will need to print via USB.

First, connect the printer to the computer with a USB cable.

Then choose Wi-Fi direct and configure it (password, IP, etc.).

The next step is to turn off the wifi on the phone and reinstall the printer in the computer by selecting WiFi direct (as the name of the WiFi network).
A second printer will appear in the Control Panel, which will only work after WiFi.

We enable sharing the net on your phone.
You need to remember that we have one wifi network with a net (shared from the phone), and the other is a printer connected (without net).
You will not be able to use the net and the printer at the same time.

It turned out to be very simple.
In the Easy Samsung Manager program you had to enable Direct wi-fi, later disconnect from the previously used network, connect to the new network, select the printer in the start menu and add a new one there. The computer will find a new printer available via wi-fi.
When printing, you need to disconnect from the network from which we have internet and connect to the network from the printer, then you lose access to the Internet. After printing, we connect to the internet sharing network again.
Thank you very much, Imprimarex, for help.
