  5. Comparing Printers • What determines the quality of the printed images? • Printer resolution: determines the quality or sharpness of printed images and text. • Dpi: (dots per inch): number of dots printed per inch. • Good quality printers are rated from 2400 to 4800 dpi.

  6. Comparing Printers • How can I determine if a printer works quickly or not? • PPM ( Pages Per Minute) Color printouts take longer to print than black and white printouts. Most printers for personal or small business use are rated from 15 to 30ppm. More memory is required to print color images and graphic-intensive documents.
