Conclusion: The USB-connected Canon Pixma MG2220 Inkjet Photo All-in-One has a sparse feature set and won't win any speed records, but it sells at a bargain-basement price and its output quality is fine for basic home or school use.
Pros: Prints, scans, and copies. Low price. Output quality suitable for basic home or school use.
Cons: Slow. Primitive, one-character display. Limited features. USB connectivity only.
