For this printer, the data must be configured bearing in mind the vertical positions of the nozzles. EPSON printers are
generally having print heads with nozzles for each color structured in the same vertical position, but this printer head takes
the Pigment Black1 nozzle as a reference point. The Pigment Black2, Magenta and Dye Black nozzles are 1/360 inch low to
the reference point. When transferring data to the printer, these offsets must be taken into consideration.
Correspondence table of raster command row and the nozzle are shown below.
