When installing a wireless printer that's already installed on one of your PCs and connected to your network, it's tempting to go Devices and Printers and clicking Add Printer. This usually works but it may only be temporary. If your router should be powered off and back on, your printer may be assigned a new IP address and it would stop printing.
The best way to install it is by using the CD that came with the printer or by obtaining the software from the manufacturer's web site.
You may just want to install the drivers without the other features, especially if it's on a laptop.
Canon, for example, offers 2 downloads for their recent printers. A full install or just the required drivers for printing and scanning.
