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.
