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.
Best Answer: A laserjet that does not print in color, but only prints in black/white. A good monochrome laser printer is the HP 1018. People who do not print color documents are better off purchasing a mono laserprinter. Although a toner cartridge will cost around $70, you can print over 2000 pages with one cartridge as opposed to around 500 pages with a $25 ink cartridge on an inkjet printer. Thus the cost per page is cheaper on a mono laser jet than the more common inkjet.
