According to my research, the printers should be technically identical. The E in DWE stands for Ecopro cartridges. You can also take out a cartridge subscription with Brother, which is currently still optional. I can't say whether it will be compulsory in the future.

Thanks for doing the research! Do you know what the difference is to the DWXL? It costs 258 and is much smaller. That's why the XL confuses me.
