Samba Server not showing up in "Network" section on Windows 7

view story

http://www.linuxquestions.org – I set up a Samba server on CentOS 6.4 and everything is working. However, I need to go into the network tab and type //192.168.x.x in order to connect to it, it doesn't show up automatically in my network tab like other PCs do, why is this? Optional question that isnt as important, how would I get a printer to show up? Do I need to first have a printer added on the computer thats running Samba server and thats it? Thanks. (HowTos)
