I bought this printer for its most attractive feature - wifi adapter. Unfortunately, it isn't a very dependable way, even thought it may seem very convenient not to have the occurence of tangled cables under the desk. In my experience, the printer has frequent problems communicating with the computer. For example, when scanning, the computer often fails to "download the application list". Troubleshooting brochures and intructions advise to restart the computer or to unplug the printer from the power source and the plug it back it. After doing so a couple of times the printer usually succeeds. In the worst case scenario, I am forced to reinstall the drivers which always helps. Communicating with the computer is only an issue for scanning, not for printing. The print quality is at best average, whereas its speed is below average. The low price for this kind of a printer is reflected in relatively pricy cartridges which dont't last very long. X4550 is a printer with irritating glitches. If not an everyday-use printer, then it is a good buy.
