1. Configured with 1,280 nozzles in 4 x 320 nozzles, the print head achieves high resolution without the grainy appearance of ink dots and is capable of printing at 1,200 dpi resolution in a staggered configuration of multiple print heads.
2. The multi-ink drop function can create various ink drop sizes from 2.5 to 9pl, and the pattern fineness completely exceeds the Epson printhead.
