Hey,
I see you are having an issue installing the Laserjet P1005 on a Windows 8 PC. I see you are using the Plug and Play driver package from HP. Are you making sure to connect through a USB cable with this printer?
What happens when you try to run this install package?
Do you get any errors?
I will need a bit more detailed information to be able to best help in resolving your installation issue, eftaxiaskostas.
