This is also known as an object-oriented graphic. Vector graphics are advantageous because they can easily be resized and stretched. In addition, vector graphics require less memory than raster graphics. Rated performance is a measure provided by the manufacturer of the maximum speed, usually the fastest speed at which the print engine can operate. However, complex pages that involve both text and heavy graphical images may require so much processing time by the printer that the printer is simply incapable of achieving rated speed.
Resolution refers to the number of dots that can be printed within a specified area.
The typical resolution for most laser output is 600 dpi. Higher-end printers, such as the HP 4000, can achieve 1200 dpi. With the increase in resolution comes better quality, lower print speeds, and increased ink usage. At 300 dpi and coarser resolutions, it is possible for the human eye to see the jagged edge caused by making an image from an array of dots. While this technique does not increase the resolution of the printer, it can improve the quality of the printed image by eliminating the rough edges.
