A printer and a computer speak different languages. The computer language must be translated so that the printers can understand it and the final print matches the image on the computer. In technical terms, Printer RIP is the software used to manage printing workflow. It helps to produce a bitmap also called a raster image from a page description language like Portable Document Format, PostScript, etc. After the bitmap is produced, it is sent to the printer for printing the output. Printer manufacturers normally provide you with a driver when you are buying a printer.
