Dear members,   I want to bring to your attention these two printer versions of the same model: For different regions in the world (maybe the difference in the PSU 110V one and 240V the other)   One is EPSON WF-3720 And the other one is EPSON WF-3720DWF   I see that EPSON only has one user guide manual for both that is the one for WF-3720 I also noticed the different cartridge model they use:   WF-3720 uses EPSON 702/702XL cartriges (eg. T702XL) WF-3720DWF uses EPSON 34/34XL cartridg
