Lexmark's Z2490 WiFi printer can be connected to a wireless network and the computers connected to that network can print from it without needing to connect via a wired Ethernet connection. This allows you to print from a laptop with wireless capabilities, such as the Dell Inspiron 1525 Notebook. The Lexmark software has to be installed first.
1). Click on the Network icon (it looks like a computer or group of bars) in the lower-right corner of your desktop. Click on the network with the Lexmark printer on it, then click "Connect."
2). Insert the Lexmark Z2490 WiFi printer installation CD into the Inspiron's CD drive. Wait for the Welcome screen to appear on your computer.
3). Click the "Install" button on the welcome screen.
4). Click through the prompts that appear on the screen. Do not change anything.
5). Click "Finish" at the end to connect to the Lexmark printer.
