When you have more than one PC, then you don't need to have printers for all of them. You just need to set up your printer to your current Wi-Fi network.
How to Install a Printer Without a Disc Drive
If your printer already has drivers, then you need not download it, and if not, then you can get it by downloading an update for your computer.
After setting the driver to the system where you want to install the printer, run the installation. Make sure that you downloaded the correct driver files.
After downloading the driver, open the computer window, and then right-click on the drive that you would like to share and then click on "Sharing." Here, you can define which computers on the network have access to the drive.
After you've set up the Sharing feature, you need to put the installation disc for the printer into the drive on the computer and access the disc from the computer.
Generally, your printer has not connected when you install the printer drivers, but for the best result follow the instructions from the printer manufacturer.
