HP 2420 - Manual (Page 207)

The default setting for Print Quality is FastRes 1200 for the HP PCL 6 print driver or 600 dpi for the
PCL 5e and PS emulation print drivers.
This setting controls resolution, which refers to the number of dots per inch (dpi) used to print the
page. As resolution is increased, the quality (clarity and visual appeal) of print on the page is
improved. However, higher resolution may also result in longer printing times. The following options
are available in the Print Quality drop-down box:
■ ProRes 1200 (180 lpi): Prints using a resolution of 1200 x 1200 with 180 lines per inch (lpi). This
prints slower than other resolutions, but has the best print quality.
■ ProRes 1200 (141 lpi): Prints using a resolution of 1200 x 1200 with 141 lines per inch (lpi). It
prints slower than other resolutions, but has the best print quality.
■ FastRes 1200: Prints using a resolution of 1200 x 600. It is faster than full 1200 x 1200
resolution, but has a slightly lower print quality.
■ 600 dpi: Prints using standard 600 dpi resolution.
The EconoMode check box can be selected in conjunction with any of the print quality settings.
When you select EconoMode, the product uses less toner on each page. Using this option might
extend the life of your print cartridge and can lower the cost per page, but the option also reduces
print quality. Using the EconoMode feature with non-HP print cartridges can result in spillage or
printer damage.
