Resolution (￿ots Per Inch)

The resolution of a raster plotter is the number of dots per inch (dpi) it can place along one of two orthogonal axes.

True ￿pi refers to the ability of the plotter to print a single dot at every location on a grid.

￿ddressable ￿pi is the ability of the plotter to selectivity position dots on a grid finer than the true0dpi grid. It is used to produce higher print quality output.

Both DesignJet 200 and DesignJet 220 plotters use two 3000dpi print cartridges. However, the DesignJet 220 has an Enhanced print mode enabling it to address a 6000dpi grid.
