Color LaserJet CP2025n:
The Hewlett-Packard Color LaserJet CP2025n is a pricey color laser printer built with the small business owner or work group in mind. At $450, the CP2025n can connect to multiple computers of a wired network and the printer produces high-quality prints, and we recommend the HP CP2025n for offices that need a dependable color laser printer.
The printer contain the four cheap toner cartridges (one black, three color) lined up in a horizontal row that use a single push-to-release tab for installation. HP provides a full set of cheap laser print cartridges in the box. A cheap black cartridge with a 3,500-page life span costs $123, while the color version is $121 for 2,800 pages. Strangely, there’s no mention of high-capacity cartridges available, so the cost-per-page equation factors out to 3.5 cents per black page and 4.3 cents for a full-color page–about average for today’s standard black prints and rather inexpensive for color prints. Finally, the CP2025n’s monthly duty cycle (maximum number of pages per month) is reported at 40,000 pages.
The HP cheap toner cartridge is quick to print color text and color graphics at 8.31 and 13.56 pages per minute respectively. Applied to real life, businesses printing a large portion of color documents will be satisfied with the print speed of the CP2025n.
The cheap black toner cartridge produces slightly more visually appealing text in smaller fonts than the cheap color toner, but remains true to the quality we expect from a professional laser. We’re particularly impressed with the graphical representations in our test subjects, which came out smooth and sharp.

Thermal ink-jet ink and ink cartridge using the ink Description
CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims priority benefit of Japanese Applications Nos. 2005-284647, filed on Sep. 29, 2005, and 2005-342686, filed Nov. 28, 2005, the entire disclosures of which are incorporated herein by reference.
BACKGROUND
An ink cartridge stores ink to be supplied to an inkjet recording device (inkjet printer). The ink cartridge is provided with an ink storage chamber that stores ink and an ink supply port that supplies ink from the ink storage chamber to the inkjet printer. The ink supply port may also function as an insertion port for an ink extraction tube. When the ink cartridge is not mounted to the inkjet printer, the ink supply port is closed by a valve so that ink will not leak from the ink cartridge.
Mounting the ink cartridge to the inkjet printer is performed by pressing the ink cartridge toward the inkjet printer. In the inkjet printer, a hollow ink extraction tube is protrudingly arranged. When the ink cartridge is mounted to the inkjet printer, the ink extraction tube engages the valve that closes the ink supply port of the ink cartridge, and the ink supply port is opened. By opening the ink supply port, the ink storage chamber and the ink extraction tube are permitted to communicate with each other, and ink is supplied to the inkjet printer via the ink extraction tube.
