The Maximum dpi print quality setting offers 4800 x 1200 optimized dpi printing.
The 4800 x 1200 optimized dpi print mode is the highest quality resolution for this
printer. When 4800 x 1200 optimized dpi is selected in the printer driver, the tri-color
print cartridge prints in the 4800 x 1200 optimized dpi mode (up to 4800 x 1200
optimized dpi color and 1200-input dpi). If a photo print cartridge is also installed,
the print quality is enhanced. A photo print cartridge can be purchased separately
if it is not included with your printer.
