The HP Officejet Pro K5400tn is a low-cost ($200), high-quality color inkjet printer targeted at small- and medium-size businesses. It’s reasonably fast, its text and graphics prints are impressive, and the ability to print photographs (though not stellar ones) is certainly a bonus. And it definitely fills a small niche. This cheap printer is best for small offices on a tight budget that don’t need certain features, such as copying or scanning, and prefer an inkjet printer over a laser one because of the ability to produce photographs.

The cheap Office jet Pro K5400tn measures 19.5 inches wide, 15 inches deep, and 8.1 inches tall, and weighs a little more than 19 pounds. Printer consists of 250 sheet input tray with adjustable paper guide. It also adds second 350 sheet paper trays. It consists of four ink cartridge, one black and three colors. A black page printed from this cheap printer costs about 1.5 cents per page and 6 cents per page for color. K5400tn does not contain an auto duplexer for double sided printing.

Text print quality is very good for an inkjet printer. The text was a rich black and characters were formed well. “Near laser” is an appropriate description; the K5400tn’s text prints were better than those of nearly all the multifunction inkjet printers. The graphics print revealed smooth color gradients along with pleasing color saturation and accuracy. HP Officejet Pro K5400tn is good for the occasional photo that may serve as a reference, perhaps for a small insurance company or a real estate agent.
