New Computer to add to Netwrok

I have a wireless network at home. I have a main hub computer connect to
internet and it has a printer contacted to it and has files I already share
with a existing laptop computer. I just brought a new laptop. It can access
the wireless and use the internet, but it cannot acces the share printer or
the sharable files. How do I add the new computer so I can use the printer
(and potentially share the files?)

what operating systems do you have on all of the computers?
