Resolution (Dots 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 Dpi refers to the ability of the plotter to print a single dot at every location on a grid.
Addressable Dpi is the ability of the plotter to selectivity position dots on a grid finer than
the trueĆdpi grid. It is used to produce higher print quality output.

Final Mode
Both DesignJet 200 and DesignJet 220 plotters use two 300Ćdpi print cartridges. However,
the DesignJet 220 has an Enhanced print mode enabling it to address a 600Ćdpi grid.
