Share folders and files on a local network

Hello
I have two machines with Zorin and I'm trying to share a folder for the other to see but it doesn't work for me.
My network is connected sharing only the internet of the house.
The funny thing is that I can see the printer of one of them, but I can't print.
What should I do? or am I missing some software that controls everything?

Hello, try following the Ubuntu section of this guide. Hope this helps.
