The color laser jet CP2025n can connect to multiple computers of a wired network, and the printer produces high-quality prints.
This attractive laser printer measures 12.7 inches tall by 15.9 inches wide by 25.9 inches deep. This printer is not easy to move as it weigh about 50 pound. The front control panel houses a small two-line black lit LCD for alerts and toner level graphics, a left and right directional pad, a cancel button, and two LEDs to alerts users of low toner and print errors. All of the ports necessary to connect the printer to a computer are on the back of the device, including the power plug, a USB port, and an Ethernet jack for wired networking among several computers. HP contains a black and color laser print cartridges in the box. A black cartridge with a 3,500-page life span costs $123, while the color version is $121 for 2,800 pages. The HP is quick to print color text and color graphics at 8.31 and 13.56 pages per minute respectively.
The cheap CP2025n makes a more consistent argument for compelling output quality rather than speed. Both black graphics and color spectrums of this cheap printer appear to be solid and well formed with crisp lineation and clean edges. As expected, the black toner produces slightly more visually appealing text in smaller fonts than the color toner, but this printer remains true to the quality we expect from a professional laser.
