The HP Photosmart C5180 all-in-one printer, scanner, and copier works incredibly fast and prints, scans and copies with true-to-life color that is hard to beat. The HP Photosmart C5180 allows users to print laser-quality documents and lab-quality photos without a computer using memory cards, USB flash memory drive and the large 2.4-inch color image display. A major drawback is the option to print in grayscale using only the black cartridge. The option is offered, but does not work as advertised. If your color cartridges are low, when you start to print the printer will require you to OK a warning that color is low, then it'll ask if it's OK to print using only black. If your color cartridge is completely empty, you can't print at all, even in grayscale, even after selecting the option to use only the black cartridge. A Google search uncovered another problem reported by multiple users- the printer constantly claimed that brand new, HP-branded ink cartridges were empty. These problems seem to have been resolved through software updates, however.
