So I need a printer where several laptops can copy. Can every printer do that? I'm no expert on this matter
You just need a printer that can be integrated into the network - either via LAN cable or via WLAN. Then you can install the printer on any computer from which you want to print.
You could even install the printer on one computer and then share it. Then this computer must always be on if you want to print from other computers. A printer with network functionality is much more convenient.
You will probably need a printer that is connected to Wi-Fi.
What do you mean by "copying"?
So you need a printer that works on the network. Almost all printers should now do this.
How much is printed? For a few pages, an inkjet printer is probably enough, here pay attention to what the cartridges cost.
A laser printer would be useful for many pages.
Do you want to print colored pages?
From my experience, I can recommend Brother multifunction devices.
The first thing you should consider is what the device should be able to do. Just print, or even scan, copy and possibly even fax? Do you need color prints or is black / white enough? Then there's the question of whether it should be a laser or an inkjet printer. Has both advantages and disadvantages. What is better for you depends, among other things. It depends on whether you will use the device frequently or only occasionally.
I will not explain this in detail now, but the information above may help you with your own research.
According to your information, it should be network-compatible. WLAN function can be very practical in this context.
