This silver coloured printer sports a futuristic design with matt grey paper flaps and a ranslucent black hood that covers the cartridge bay. This hood opens just like the hatch of a car and then slides along the body surface. How-ever, the printer has a rather large foot print. HP has revised the print-er design to include support for new types of standard car-tridges and photo-cartridge. The cartridge installation is simple and requires no force for getting them in place. The cartridges use a smaller drop size and the printer comes with PhotoRet IV which means it provides six basic colours instead of four. Also, PhotoRet IV has 1.2 million colours as opposed to the 3,500 in PhotoRet III mode. Depending on the car-tridge, the printer works in differ-ent modes. With stan-dard car-tridges the printer shifts to PhotoRet III (for text printing); with Photo Cartridge the printer works in PhotoRet IV (for printing images). The printer automatically adjusts the print resolution depending on the paper quality.To print at the maximum rated resolution (4800x1200) the paper type has to be selected manually. The printer has support for A4 sheets and up to 100 sheets can be loaded in one go. The paper output flap can handle 50 sheets, however, the locking mechanism is not strong enough to hold this weight. The printer has an 8 MB buffer and has an IEEE 1284-B parallel port and a USB port for connecting to a PC. In our tests, it printed text in black and white mode at a relatively good speed of 9 PPM. In the fast draft mode, it was exceptionally fast, scor-ing 13 PPM compared to the normal mode of operation. In the combination document test, it printed the test file under a minute in the greyscale mode, which is pretty fast. It surprised us by taking the same amount of time to print this file in colour mode! It took approx-imately 300 seconds (5 min-utes) to print the test image, which is fast enough for a printer in the mid-range cat-egory. It took around 180 seconds (3 minutes) to print the image in greyscale. The print quality was crisp and clear, with no smudging or jarring. The image quality test showed slight saturation in the colour reproduction. The HP 5550 delivers good printing speed, especially for text and combination documents. Though the image printing speed is a bit slow, it makes up for this with good image quality—a good choice if you want a printer for daily office printing work and to occa-sionally print photographs.
