help needed regarding interfacing project

hi everyone,i'm a new member here,and i'm seeking help regarding my computer interfacing project.

the project is "wireless data communication between 2 pcs".as some pre-built hardwares are difficult to get in my country,i'm seeking some easier solutions,so i'v chosen parallel port and rf transmitter reciever for the project.

now,can anyone give me some info on,rf transmitter and reciever circuits and schematics?also,help on how to trasmit data using parallel port and then through rf circuit is most welcome.

thanks in advance.

guys,i've decided to use the hope RFM12B module.i think it needs some setup/configuration...can anyone help on that matter?
