The PIXMA MP520 is a general purpose all-in-one printer, scanner, copier from Canon. Primarily designed for a small amount of home/home office use due to its slow speed and small ink cartridges, the MP520 features an improved printing system from earlier models, dropping the two cartriage system for a faster, more complex 4-cartridge design. With the same improved scanner the MP520 continues to have memory card support with a larger 2.0" LCD display for previewing and selecting photographs to print without the need for a PC. Like the majority of Canon models, the MP520 allows users to print directly from their digital cameras, regardless of brand, without the need for a PC. It also allows for oversized scanning.
