TEM (a, b, and c) images of prepared mesoporous silica nanoparticles with mean outer diameter: (a) 20nm, (b) 45nm, and (c) 80nm. SEM (d) image corresponding to (b). The insets are a high magnification of mesoporous silica particle.
The Definition of a Monochrome Laser Printer. Monochrome laser printers are machines that print text and images from computers by using a laser beam to control where a single color is applied to paper. They're often faster than other types of printers and can generally produce large numbers of black-and-white documents cheaper than other printers.
Using these numbers, we calculated the black-and-white CPP at 2.2 cents and the color per-page cost of operation at 13.6 cents. The monochrome numbers are middling-to-okay, but the color CPP is still far too high if you plan to print many color pages. The problem for HP here is two-fold.
