thank you for your answers.
My router is D-Link DSL-6740U.ftp://ftp.dlink.ru/pub/VDSL2/DSL-6740U/Description/DSL-6740U_B_T2A_User%20Manual_1.0.10_24.05.13_EN.pdf .
I haven't so much experience with this kind of problem, and at the beginning I thought that the only possibility was to setup of the router to fix the assignment of the IP addresses..
But now I learned many things that I did not know from your answers .(mDNS, Zero-configuration networking, ..).
Now I have to study quite a lot.
I will ask again if I need.
Thank you
Angelo

If your router provides DHCP it usually provides a DNS service as well. You should log into your router and check the menus. Which router model are you using?

Printers with an Ethernet connection usually by default observe for DHCP before assigning a random IP. So your printer should get its IP from your router as well. Your printer most likely tells the router’s DNS also its symbolic name, most likely some combination of manufacturer and model. The printers configuration page will tell you, or you can have a look into the device list of your
router which should show the IP address and the symbols name (smoother like e.g. „brother-mx“). So you might use that symbolic name in the printer configuration of your workstations.

you can manually assign fix IP addresses to network devices. You router will find out by itself about IP addresses in use and won’t offer them in the DHCP process.
Generally it’s a bad idea to mix devices with manually assigned IPs and devices using DHCP, at least if you have to manage more than 10 devices or so. After some time you forget some details and/or there is an update which changes some details, and you may run into issues. IT’s better to have a central management device, which is the router. Usually, you can configure the router to always assign the same IP address to a device depending on its MAC address.
