Hi Chailn,
I assume if you're asking, then you don't have the installation instructions that comes with it. And you don't have the CD which has the necessary driver.
Get the driver here. You'll need to chose your operating system. Save the driver file to a disk.
1. Shut down windows and power off everything with a switch.
2. Connect the printer to your PC with the cord that came with the printer.
3. Connect the printer to a power supply.
4. Turn on the printer and any other periferals you have.
5. Power up your PC.
Windows should detect the new hardware connected and will attempt to locate the driver. If Windows can not locate the driver, you will need to help it by browsing to the location you saved the driver. It should pretty much take care of the rest on its own from this point.
Be sure you have ink cartridges installed before turning on the printer.
Hope this helps,
Randy
