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.
Print color as black (Acrobat Pro, Pro Extended, and 3D Version 8 only | Windows only) On Windows, you can print all of the non-white colors in your PDF file as black, resulting in a simple monochrome printout. Printing as black is useful for printing PDFs that contain text only, or for printing engineering drawings that have lightly colored lines. Choose File > Print. Select Print Color As Black.
