A collection of techniques used in many
laser printers to enable the
printer to print at a higher
resolution than normal. Most laser printers have
printer engines that print at either 300
dpi (dots per inch) or 600 dpi. Using clever
algorithms that recognize curved lines, a printer with resolution enhancement can produce
output whose resolution appears to be much higher than the print engine's rated resolution. This is why many printer manufacturers characterize their printers with two resolution ratings: the
engine resolution and the
effective resolution. A common resolution enhancement technique is to vary the size of the dots.
