Hey,
First of all, I am really inexperienced about all these things. I have a MacBook from 2009 with OSX Lion and a PC Windows 7 x64. I have got a time capsule (https://www.mikepalmer.net/wp-content/uploads/2011/12/apple-time-capsule.jpg) connected to my router and then another router in my room (probably working as an acces point) to which I wirelessly connect my Windows 7.
The thing is that I can see the printer (HP Laserjet P1005) from my Mac but I don't know how to add it to my windows. On a previous PC I added a printer to the time capsule's IP 192.168.1.2 and printed with a considerable delay that way.
As you can see I don't understand how networks work, how IP's work, or how ports work in this matter.
Any help will be much appreciated!!
