How to Connect My Laptop to My Desktop Computer Printer Via a Wireless Connection

Install the printer driver in both the laptop and the desktop. Insert the CD that came with the printer when you purchased it, and follow the prompts to install it.
Connect the printer to the desktop through its USB cable. The USB cable comes with the printer when you bought it. The desktop should recognize the printer once the two are connected.
Place a Wi-Fi router within 100 feet of both computers, and turn on the Wi-Fi connections to both your desktop and laptop. If your desktop doesn't have Wi-Fi, connect it via Ethernet port. If necessary, enter the user name and password for your router to log on.
Share the printer connected with the desktop to the laptop. Click on the 'Start' button of your desktop. Click on 'Control Panel,' and select 'Printers and Faxes.' Choose the name of the printer that is connected to the desktop, and then right click on it, then click 'Properties.' Go to the 'Sharing' tab, and enable the sharing of the printer. After that, hit the 'Enable file and printer sharing' button.
Modify the printer settings on the laptop. Go to the laptop's 'Control Panel' and open 'Printers and Faxes.' Click on the 'Add Printer' button. A wizard will be opened to guide you in adding the printer to your system. Make sure that the name of the computer that you wish to add on your printer settings is the same as the name of the printer that you have connected to the desktop.
Try printing a test page from the laptop. If it does not work, change the name of the printer that you have added on its setting. It should match the name of the shared printer on the desktop.
