. This diagram illustrates the relationship between the reference pixel and device pixels (called "dots" below). The image depicts a high resolution (large dot density) laser printer output on the left and a low resolution monitor screen on the right. For the laser printer, one square reference pixel is implemented by 16 dots. For the monitor screen, one square reference pixel is implemented by a single dot. Return to image.
