The type of printer ink to be replaced inside an empty cartridge depends upon the brand and model of an inkjet printer. Every brand and model is designed to work with a particular type of inkjet printer ink that is ill suited for other brands and models.

The inkjet printer of today is equipped to produce both color and black-and-white prints on the same paper. Color inkjet printer ink is available in a single-cartridge system or a multiple-cartridge system. In a single-cartridge system all the colors of printer ink are bundled inside a single cartridge. In a multiple-cartridge system different cartridges are used for different colors.

But the PSP s 4.3-inch screen is even better - and not just because it s bigger. Its wide-screen aspect ratio is perfect for movies and videos.

Then there s storage capacity. The iPod has a 30GB or 60GB hard drive, while the PSP doesn t have a built-in hard drive at all. Instead, it stores data on Sony s Memory Stick Pro Duo flash media cards, which max out at 2GB - enough for two or three feature films or several hours of TV recordings, after you ve compressed and encoded the video for PSP (more...)
