Imageprint 6.1, and newer, allows you to replace the Lt. Lt. Black ink cartridge with the Matte Black ink cartridge. This configuration allows you to print on demand with either Photo Black or Matte Black ink. You no longer have to change back and forth between black inks on the EPSON Stylus Pro 4800, 78xx and 98xx printers. These EPSON Stylus Pro 220 mL cartridges are for use as replacements for the Lt. Lt. Black cartridges for the EPSON Stylus Pro 4800, 78xx and 98xx printers. These cartridges will only work in the Lt. Lt. Black slot on these printers. These cartridges will NOT work in the regular black ink slot.
For the EPSON Pro 4800 use product code MB48IP.
The EPSON Pro 4880 cannot use these cartridges
For the EPSON Pro 78xx/98xx use product code MBX8IP.
