Samsung / m2070w - Printer connection via WiFi Direct / Ad-hoc

Hello,
At the beginning of 2018, there was a topic related to connecting the Samsung M2070x printer via WiFi Direct (without a router). The topic has been closed, so I am opening it as a new one.
Well, as Imprimarex and grala1 wrote, I went through the next steps of the installation and stopped while entering the WPS PIN. I copied the number from the previously printed Network Configuration, but this number does not allow a wireless connection. Colleagues / Koleżanki do you have ideas on how to solve a given problem?

Insert the installation disk into your computer-setup-program installation-select wireless network connection via USB cable-or network connection-next-computer will find printer and network after connecting USB cable. In the window, it will show you the current network, whether in the company or at home, the name of the network and the IP address will be given in the name as the printer got from the machine. IMPORTANT if it does not find the name of your network, because it turns out that the neighbor or another computer has a stronger signal and works as a router (you choose the option to change network settings) - then - in the next window you will see networks and devices with Wi-Fi access Fi find your network and click on it. -new- enter the NETWORK PASSWORD - -further- (for security check by unchecking hide Password if you entered it correctly) check again hide password - next- will show you in the window searching for a wireless network. In the next window you will see PRINTER DATA, eg M2070W, under the password - next- and here in the next window you have the command to disconnect the USB cable, what do you do. You still have printer software installation options. You install - go on - The printer and installer are doing what they need to do, blah blah blah installation in progress ........... In the next window you can select print test page and quit. Best regards and good and quick printing. You already have the form on the network. now in the START MENU find (devices and printers) only check if it displays your printer should be marked (with a green tick) which means that it is set as default. they open the program, e.g. Notepad, a text file, you give print, in the option you give the Samsung M2070M printer and it's ready.
