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 cartridges (eg. T3471)
Please if someone can confirm that chipless firmware available for WF-3720 as found on chiplesssolutions.com is also working for WF-3720DWF?
