You have multiple computers at home but you might only have one printer connected to a USB port to one of the PC. Then when it comes that you want to print something from another PC that has no printer attached to, you will need to copy the file to the PC that attached to the local printer for the printing.
Imagine you can print to the same one printer using all your home computers, then you need to setup a home LAN and make a shared printer.
This how-to tutorial only assumes that you have your home workgroup network already setup. Then you can follow these simple steps to setup a shared local printer:
Step 1
From Control Panel, double click “Printers and Faxes” to open. You will see a list of available printers in a window.
Step 2
Select the printer you want to share to the rest of the computers at home. Right click on it, and choose “Properties”, a printer property window will open.
Step 3
On the top of the tabs, click on the “Sharing” tab, and select the radio button “Share this printer”, then enter a Share name. The name could be the printer model or any name you like. Then click Ok to save the settings to close the window.
Step 4
Now you can add this shared printer to the rest of the computers at home by adding this network path, from Start, choose Run and enter: pcnameshareprintername
Where the pcname = the name of the pc that has the local printer attached to, and the shareprintername is the name of the printer that gave it the name for sharing. You will also need to type in the double back slashes as well.
